This book was released on with total page 154 pages. Available in PDF, EPUB and Kindle. Book excerpt: : This book is based on research conducted on the growth and characterization of nonlinear optical crystals. Due to the significance of crystals in contemporary technology, crystal growth has been the focus of extensive research in both solid-state physics and materials science. This book serves as an introduction to the growth phenomena, specifics of growth processes, nonlinear optical phenomena, and characterization methods that are being used for the analysis. The book is divided into three chapters: The first chapter focuses on the experimental techniques of crystal growth. It outlines the several ways that crystals grow based on the phases they go through, such as solid-solid phase transition, liquid-solid phase transformation, and vapour-solid phase transformation. The optimization methods for growing high-quality single crystals are thoroughly presented. The benefits and drawbacks of methods of growth are reviewed. The second chapter explains the theory of nonlinear optical phenomena. The selection criteria for nonlinear optical materials are reviewed. The history of nonlinear optics and the various types of nonlinear optical materials are discussed. The role of amino acids in the formation of nonlinear optical crystals is well explained. The third chapter discusses characterization procedures that are essential in determining the quality of crystals. The several characterization mechanisms including the molecular structure, chemical composition, surface morphology, optical properties, dielectric properties, mechanical behavior, and thermal properties necessary for crystal analysis are described. We hope that this book will be valuable to researchers and students.

This book was released on 2018-07-05 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: Experiments were carried out to grow 3.Nitroaniline (m.NA) crystals doped with 4.Nitroaniline (p.NA) and 2.chloro 4.Nitroaniline (CNA). The measured undercooling for m.NA, p.NA, and CNA were 0.21 tm K, 0.23 tm K, and 0.35 tm K respectively, where tm represents the melting temperature of the pure component. Because of the crystals' large heat of fusion and large undercooling, it was not possible to grow good quality crystals with low thermal gradients. In the conventional two-zone Bridgman furnace we had to raise the temperature of the hot zone above the decomposition temperature of CNA, p.NA, and m.NA to achieve the desired thermal gradient. To avoid decomposition, we used an unconventional Bridgman furnace. Two immiscible liquids, silicone oil and ethylene glycol, were used to build a special two-zone Bridgman furnace. A temperature gradient of 18 K/cm was achieved without exceeding the decomposition temperature of the crystal. The binary crystals, m.NA-p.NA and m.NA-CNA, were grown in centimeter size in this furnace. X-ray and optical characterization showed good optical quality. Singh, N.

Book excerpt: In the modem world, the development of science & technology in many areas has been achieved through the growth of single crystals. Large sized single crystals are essential for device fabrication and efforts are taken to grow large single crystals in short duration with less cost. Nonlinear optical (NLO) materials are expected to play a major role in photonics including optical information processing, sensor protector applications, data storage ... etc. Some organic compounds exhibit large NLO response, in many cases, orders of magnitude larger than widely known inorganic materials. They also offer the flexibility of molecular design and the promise of virtually an unlimited number of crystalline structures. The present book is aimed towards the development of NLO single crystals of L-Valinium picrate (LVP), L-Histidine hydrochloride monohydrate (LHHM), L-Serine sodium nitrate (LSSN), Bisglycine hydrobromide (BGHB) and Picolinic acid hydrochloride (PHCL) which are all excellent NLO materials are exhibiting NLO property more than that of KDP, and these grown materials can be used as a better replacement for KDP to find applications in the field of opto-electronics.

Book excerpt: The present book is aimed towards the development of NLO single crystals of p-Toluidine p-Toluenesulfonate, L-Proline Succinate, L-Arginine semicarbazide and L-lysine sulphate are exhibiting NLO property more than that of KDP, and these grown materials can be used as a better replacement for KDP to find applications in the field of opto-electronics. These crystals belong to the amino acid group, which exhibit the nonlinear optical (NLO) property remarkably. The characterization studies include single XRD analysis, UV analysis, mechanical and dielectric studies of the grown crystals. The dielectric and photoconductivity measurement were also carried out for the grown crystals to probe the nature of the conductivity. Hence, the grown crystals are to be confirmed for the single crystalline nature using XRD technique. From UV spectral analysis the required transmission range for the Second Harmonic Generation (SHG) and optical band gap have been estimated.The mechanical, dielectric, and photoconductivity studies were carried out to probe the mechanical strength and polarizability nature of the grown crystals.
Download or read book Growth Characterization and Irradiation Effects of Organic Nlo Crystals written by P SRINIVASAN and published by LAP Lambert Academic Publishing. This book was released on 2011-04 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: New materials are the lifeblood of solid state research and device technology. Contrary to what many believe, new materials are not usually discovered by device engineers, solid state theorists, or research managers; they are mostly discovered by crystal chemists who are crystal growers. Some physical phenomena are only exhibited in single crystals and can only be studied and understood in single crystals. Thus the crystal grower - especially if he develops a proficiency in relating structure, bonding and other chemo-physical considerations to properties of interest - is in a key position in determining the direction & success of solid state research and ultimately - technology.There is a need for new lasers with exciting combination of light properties such as wide spectral tuning ranges & large bandwidth for communication systems. While a variety of materials have been studied for their NLO activity, the organic materials have been receiving the maximum attention because of their ultra fast response time, photo-stability and large first order hyper polarizability values.In this view some new organic compounds have been synthesised, grown, characterised, irradiated & discussed

Download or read book KDP Family Single Crystals written by L.N Rashkovich and published by CRC Press. This book was released on 1991-01-01 with total page 230 pages. Available in PDF, EPUB and Kindle. Book excerpt: The KDP family of single crystals is composed of compounds of alkali metals with light or heavy (hydro, deutero) water and oxides of phosphate or arsenate, including ammonium, potassium, rubidium and caesium dihydro- and dideutero-phosphates, and similar arsenates. While not occurring in nature, their production exceeds that of any other water-soluble crystals and the demand for bigger and more optically pure crystals is ever increasing. KDP-Family Single Crystals is a comprehensive investigation of the crystallization mechanism for these systems. The first part of the book collects the majority of the available data on the physico-chemical analysis of these systems. This is complemented by a review of contemporary concepts related to the crystal growth dislocation mechanism under the influence of impurities, changing supersaturation, and temperature. This is not only relevant to the growth of KDP single crystals but to the majority of crystals grown from low- and high-temperature solutions. Finally, attention is given to the important problem of speeding up the production processes for the growth of these crystals while maintaining the quality of the crystals. The in-depth coverage that KDP-Family Single Crystals provides to the art of crystal growth techniques makes it an essential reference work for all those working in the field of crystal growth and to those using KDP-family crystals in quantum electronics devices.
