Investigations on certain pyridine based organic single crystal complexes for optoelectronic applications

Abstract

The technology and science of crystal growth have progressed rapidly in recent years to develop new nonlinear optical materials The desire to utilize the properties of these materials in applications such as telecommunications optical data storage and optical information processing has created need for new materials with very large second order susceptibilities Crystals have been playing a vital role in modern science and technology because of their practical application in almost all branches of industry and in all walks of daily life The importance of crystal growth for the advancement of technology can be realized from the fact that crystals are used in almost all electronic devices manufactured by electronic industries The present work is presented in six chapters in the thesis and a brief note of the research work presented in the different chapters are given below Chapter I presents a brief introduction about crystal growth techniques and in particular the growth from solution Overview of historical perspectives of nonlinear optical phenomenon are also discussed in this chapter Chapter II deals with the growth of single crystal 2 amino 6 methylpyridinium 2 hydroxybenzoate 2A6MP2H crystals grown by slow evaporation solution growth technique newline
