INVESTIGATION ON VARIOUS STUDIES OF THIOUREA DOPED L-ALANINE CADMIUM CHLORIDE CRYSTALS

Abstract

The growth of L-alanine cadmium chloride (LACC) crystals was carried out by solution method with slow evaporation technique. Nucleation kinetic studies were performed for the samples to understand the nucleation process. The grown crystals were subjected to structural, mechanical, thermal, electrical and spectral properties. FTIR and ultra violet – visible (UV-Vis) spectral studies have been carried out to find the suitability of the grown crystals for device fabrication. AC conductivity values of the samples were measured using an LCR meter at different frequencies and temperature. Activation energy has been calculated for all the samples. The mechanical parameters like work hardening coefficient, stiffness constant and yield strength of the samples have been determined. Third order nonlinear parameters like nonlinear refractive index, nonlinear absorption and third order susceptibility were determined by Z-scan technique for pure and doped samples of LACC.
