Abstract

In the modern era materials with high NLO efficiency, better mechanical and thermal properties are on leading edge and highly demanded for their efficient use in optical communication and fibers optics. In the present course of work, authors have grown successfully single crystals of L-alanine strontium chloride trihydrate(LASRT) by slow evaporation solution and slow cooling techniques so as to meet the demand of industries. Structure of the grown crystal with lattice parameters were confirmed by employing powder XRD technique. Mechanical strain present in the lattice is determined as -7.066 x 10(-2) by Williamson-Hall relation. The newly grown crystals were subjected to HRXRD to assess crystal perfection and various types of defects. In this research, quality of the grown crystals is found moderately good. The specimen has better transmission nearly 44% as indicated by UV-Vis spectra. Various remarkable parameters like optical band gap, reflectance, refractive index, extinction coefficient and electrical susceptibility are determined. Some important electronic parameters are calculated by using Claussius-Mossottee relation. Thermal properties were also investigated in detail by subjecting the crystals to TGA/DTA measurements. By photo acoustic analysis, thermal diffusivity (alpha) is found 1.8816 x 10(-6) m(2)/s which indicates large heat bearable capacity of the grown sample. Mechanical stability of LASRT is determined larger than already reported LOMHCl and LLHBr single crystals by Nano-indentation technique. Results for nonlinear optical testing, crystalline perfection and optoelectronic parameters indicate its suitability for laser applications.
