Book excerpt: In this book the authors first provide a summary of the natural sources available for the synthesis of zinc oxide nanoparticles, enlisting some plant-mediated synthesised zinc oxide nanoparticles showing promising antimicrobial, antioxidant, cytotoxic and photocatalytic properties. Important technological opportunities and challenges emphasizing the electrical and optoelectronic features of elongated zinc oxide nanoparticle nanosystems are reviewed. The various nonlinear optical phenomenon observed in zinc oxide thin film, including nonlinear absorption, nonlinear refraction, nonlinear scattering and harmonic generations are introduced. Selected literature on the use of zinc oxide nanoparticles for the immobilisation of enzymes is reviewed, as well as the use of zinc oxide nanoparticle/enzyme systems in the fabrication of biosensors. The authors explore transition metal doped zinc oxide nanoparticles for a wide range of catalytic organic reactions, further exploring their catalytic applications for organic transformations at mild reaction conditions. The basic concepts behind the development of nanostructured zinc oxide nanoparticles, including the solid state reaction, hydrothermal method, solvothermal method and co-precipitation method are discussed. Lastly, a facile, eco-friendly synthesis of zinc oxide nanoparticles using the peel extract of Musa paradisiaca L, Punica granatum L, and Citrus reticulata Blanco as bioreducing agent is reported.

Available in PDF, EPUB and Kindle. Book excerpt: The semiconductor material of zinc oxide (ZnO) has been studied intensively for decades due to its numerous unique electrical and optical properties, such as wide bandgap, high exciton binding energy at room temperature, and high refractive index. These properties can lead ZnO material to the applications of electronics and optoelectronics. More importantly, the realization of various kinds of ZnO micro- or nano-structures, makes ZnO capable to improve the electrical and/or optical performances of the devices. Different micro- or nano-structured ZnO has attracted much attention from researchers worldwide in the recent years as this will bright the future of ZnO in the applications of light emitting diodes (LEDs) and solar cells. And thus, developing a simple, low-cost, and environmental friendly method to grow ZnO having desired micro- or nano-structures is of great importance in the research field of ZnO material, and this becomes a key issue when a large-scale production is required in the industry. Meanwhile, the parameter control during the synthesis procedure is essential to be modified and clarified. The main focus of this thesis is on developing a simple, inexpensive, and solution based thermal method to grow spherical shaped ZnO particles having uniformly distributed size. The growth parameters for controlling the size and shape, such as the hydrate, solvent, salt concentration, reaction temperature, reaction time, seed solution, and heating rate, are experimentally studied and clarified in this thesis. This method has the advantage of large-scale production and good reproductivity with low requirements in regard to the facilities and experimental conditions in industry. At the same time, the related growth mechanism of the submicron ZnO spheres is studied, derived, and theoretically analyzed in this thesis, based on the observation in the experiments. Another focus of this thesis is on the study of the surface morphologies and optical properties of the synthesized ZnO particles. The surface morphologies are analyzed by the techniques of field emission scanning electron microscopy, X-ray diffraction, and transmission electron microscopy. The optical properties of the synthesized ZnO particles are experimentally investigated by Raman spectroscopy and photoluminescence at room temperature. Furthermore, the related luminescence mechanism is theoretically studied, modelled, and presented in this thesis. In order to explore the applications of the synthesized ZnO spheres, the composite of ZnO/V2O5 (zinc oxide/vanadium pentoxide) is designed, fabricated, experimentally investigated, and theoretically analyzed. The experimental results indicate that this transition metal oxide mixture can be developed to create a group of new light emission materials with high efficiency. Moreover, a silicon-based ZnO light emission device is presented in this thesis, reporting that visible light emission is observed at room temperature from the ZnO material which deposited on the hot electron emitting substrate (HEES). Finally, some of the future works of this research are suggested.

This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Zinc oxide (ZnO) is a well-known and intensively studied material for optoelectronic applications in the ultraviolet (UV) spectrum region due to its wide band gap energy - 3.34 eV. However, the UV applications based on nanostructured ZnO present a big challenge due to the small size of the nanostructures i.e. a large surface-to-volume ratio resulting the appearance of the visible emission originated from the surface defects. In the last decades, the progress concerning the fabrication of UV-emitting ZnO nanostructures was carried out through the high temperature gas phase based approach. However, the size and shape control of ZnO nanostructures obtained with this approach is still difficult. Taking into account the state of the art in the optics based on ZnO nanomaterials, this Ph.D. thesis demonstrates the development of new supercritical fluids based approach for the synthesis of ZnO nanostructures with UV-emitting only PL properties. First of all in this thesis, we have developed continuous supercritical set up from micro- up to millifluidic reactor dimension for the synthesis of a larger quantity of UV-emitting ZnO nanocrystals (a gram scale per day). The influence of reactor dimension associated with hydrodynamics on physico-chemical characteristics was investigated. ZnO nanocrystals formation mechanism was studied as a function of the residence time in our continuous supercritical fluids process for the understanding of the nucleation and growth of the nanocrystals. Moreover, ZnO nanocrystals formation mechanism determines UV-emitting properties of this material. The optical properties at room and low temperature were deeply investigated with comparing to the PL emission of several types of ZnO particles and single crystal for the understanding of the nature of UV emission.

Available in PDF, EPUB and Kindle. Book excerpt: From the Introduction: Nanotechnology and its underpinning sciences are progressing with unprecedented rapidity. With technical advances in a variety of nanoscale fabrication and manipulation technologies, the whole topical area is maturing into a vibrant field that is generating new scientific research and a burgeoning range of commercial applications, with an annual market already at the trillion dollar threshold. The means of fabricating and controlling matter on the nanoscale afford striking and unprecedented opportunities to exploit a variety of exotic phenomena such as quantum, nanophotonic and nanoelectromechanical effects. Moreover, researchers are elucidating new perspectives on the electronic and optical properties of matter because of the way that nanoscale materials bridge the disparate theories describing molecules and bulk matter. Surface phenomena also gain a greatly increased significance; even the well-known link between chemical reactivity and surface-to-volume ratio becomes a major determinant of physical properties, when it operates over nanoscale dimensions. Against this background, this comprehensive work is designed to address the need for a dynamic, authoritative and readily accessible source of information, capturing the full breadth of the subject. Its six volumes, covering a broad spectrum of disciplines including material sciences, chemistry, physics and life sciences, have been written and edited by an outstanding team of international experts. Addressing an extensive, cross-disciplinary audience, each chapter aims to cover key developments in a scholarly, readable and critical style, providing an indispensible first point of entry to the literature for scientists and technologists from interdisciplinary fields. The work focuses on the major classes of nanomaterials in terms of their synthesis, structure and applications, reviewing nanomaterials and their respective technologies in well-structured and comprehensive articles with extensive cross-references. It has been a constant surprise and delight to have found, amongst the rapidly escalating number who work in nanoscience and technology, so many highly esteemed authors willing to contribute. Sharing our anticipation of a major addition to the literature, they have also captured the excitement of the field itself in each carefully crafted chapter. Along with our painstaking and meticulous volume editors, full credit for the success of this enterprise must go to these individuals, together with our thanks for (largely) adhering to the given deadlines. Lastly, we record our sincere thanks and appreciation for the skills and professionalism of the numerous Elsevier staff who have been involved in this project, notably Fiona Geraghty, Megan Palmer and Greg Harris, and especially Donna De Weerd-Wilson who has steered it through from its inception. We have greatly enjoyed working with them all, as we have with each other.
