Available in PDF, EPUB and Kindle. Book excerpt: Recently, the preparation and characterization of materials in the nanometer scale has become challenging in the field of material science. Materials in the micrometer scale mostly exhibit physical properties as same as that of bulk form; however materials in the nanometer scale may exhibit physical properties distinctively different from that of bulk. Semiconducting nanoparticles have attracted widespread attention because of their special optical and electronic properties arising from the quantum confinement of electrons and large surface area. Among the semiconductor materials, Zinc Sulphide (ZnS), shows various luminescence properties such as photoluminescence, electroluminescence and thermoluminescence. Hence, ZnS is a traditional phosphor widely used in flat-panel display, electroluminescence devices, infrared windows, sensors and lasers. When ZnS material is doped with transition or rare earth metal ions, it is possible to modify its physical properties. For doped nanocrstalline semiconductor materials, quantum confinement effects in the energy states also produce unusual optical behaviour. In this book, undoped and some transition metal ions doped ZnS semiconducting nanomaterials were synthesized by microwave-assisted solvothermal method. To prepare the undoped ZnS nanoparticles, zinc acetate and thiourea were used as the precursor materials and ethylene glycol was used as the solvent. The solvothermal method used in this present work is an effective method for preparing metal sulfides under mild conditions, which is a simple, cheaper and convenient method. ZnS materials doped with transition metal ions were also synthesized by the same method. In the present work, ZnS material was doped with manganese, copper, cobalt and indium in four different concentrations. The microwave treated precursor materials, after washing with de-ionised water and acetone and after annealing leads to fine nanocrystalline powder.

Available in PDF, EPUB and Kindle. Book excerpt: Due to their unique optical, thermal, catalytic, magnetic and electronic properties, nano-sized semiconductors have a huge potential in a great number of technological applications, ranging from photovoltaics and photocatalysis to biosensors and medicine. In the last couple of decades, the synthesis and characterization of these materials has been of key interest not only to materials scientists but also to researchers working in the field of physics, chemistry, molecular biology and medicine. The main focus of the present book is the characterization of a number of nano-semiconducting materials, using such techniques as powder X-ray diffraction, UV-visible spectrophotometry, Raman spectrometry, scanning electron microscopy, transmission electron microscopy and vibrating sample magnetometry. The materials studied include ZnS, TiO2, NiO, Ga doped ZnO, Mn doped SnO2, Mn doped CeO2 and Mn doped ZrO2. Of special interest has been the analysis of the electron density distribution within the nano samples. The results give deep insights into the atomic structures on which these crystals are based and on the binding characteristics between the atoms and the ways in which these characteristics can be changed. As the decisive properties of these materials depend upon the electron density distributions and their variations due to sample preparation specifics, temperature and the presence of doping elements, these results give important hints on the direction in which further research should be directed.

Download or read book Quantitative EPR written by Gareth R. Eaton and published by Springer Science & Business Media. This book was released on 2010-04-10 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is a growing need in both industrial and academic research to obtain accurate quantitative results from continuous wave (CW) electron paramagnetic resonance (EPR) experiments. This book describes various sample-related, instrument-related and software-related aspects of obtaining quantitative results from EPR expe- ments. Some speci?c items to be discussed include: selection of a reference standard, resonator considerations (Q, B ,B ), power saturation, sample position- 1 m ing, and ?nally, the blending of all the factors together to provide a calculation model for obtaining an accurate spin concentration of a sample. This book might, at ?rst glance, appear to be a step back from some of the more advanced pulsed methods discussed in recent EPR texts, but actually quantitative “routine CW EPR” is a challenging technique, and requires a thorough understa- ing of the spectrometer and the spin system. Quantitation of CW EPR can be subdivided into two main categories: (1) intensity and (2) magnetic ?eld/mic- wave frequency measurement. Intensity is important for spin counting. Both re- tive intensity quantitation of EPR samples and their absolute spin concentration of samples are often of interest. This information is important for kinetics, mechanism elucidation, and commercial applications where EPR serves as a detection system for free radicals produced in an industrial process. It is also important for the study of magnetic properties. Magnetic ?eld/microwave frequency is important for g and nuclear hyper?ne coupling measurements that re?ect the electronic structure of the radicals or metal ions.

Available in PDF, EPUB and Kindle. Book excerpt: This volume of a book Applied Aspects of Nanophysics and Nano-engineering is partially composed of short communications proceedings of international symposium Nanophysics and nano-engineering 2017 (venue: Mining university), and full-sized chapters, covering selected topics in depth. A variety of phenomena are described in this book. Smart nanostructured coatings, methods of synthesis based on both top to bottom (plasma deposition, remote methods) and bottom to top approaches are covered, as well as modeling approaches and analytical techniques. As before, ecological issues are highly addressed, such as materials for water purification and pollution prevention. Permanent interest in fullerenes as to one-dimensional carbon-based structures arises from their ability to be relatively easily modified by species of interest, for the purpose of bio-substrate delivery. Graphite exfoliation is utilized as a method to produce graphite nanoparticles and the modelling of fullers is reported. Issues of dielectric relaxation of solids have been a stunning topic for at least a few decades, and even now the interest in the dielectric relaxation approach seems to increase. This is because of the sensitivity of this non-destructive method to the conformational changes of flexible molecular moieties, brushes, and interchain segments. This avenue was focused on materials appliances of the method and technical development of the method and resolution, as well as the materials studied. Semiconductor technologies discussed in the book were related to developing solar concentrator systems (silicon technologies), heterojunction solar cells of eutectic gallium arsenide solid solutions for the development of alternative heterostructures based on the tunneling effect. Exotic semiconductors diamonds with delta-doped layers known for their high temperature resistance are studied via capacitance measurements. Directional crystallization was studied to produce rear-Earth compounds with anisotropic properties for the application of thermoelectric materials. Findings in sorption properties of clay minerals with singlet oxygen is underestimated as global in terms of environmental factors. Oil shale and oil shale ash Baltic basin studies are reported. Materials with magnetic properties synthesized by the sol-gel method are based on varrium-titanium ceramic and are studied via a variety of powerful experimental methods: SEM, XRD, SAXC, and SAPNS. Findings in the surface modification of zinc oxide films are modified by selenium. A special experimental setup is made possible using an ambient pressure approach without isolating the atmosphere to synthesize the hierarchically ordered surface structure. Interface properties related to water absorption on an aluminum surface are analyzed, and they are of interest for tribology applications of organopolymer compositions. Composite nanostructured materials for solar concentrator systems are discussed, as well as compounds for thermionic energy converters. It is believed that this book provides an unbiased sketch of progress in nanotechnology and related areas.
