Synthesis, Theoretical, Mechanical and Dielectric Property of L-Serine Sodium Nitrate NLO Single Crystal

Abstract

Single crystals of non-linear optical material, L-Serine Sodium Nitrate (LSSN) have been grown by slow evaporation technique. The crystal system and lattice parameters were found from single crystal X-ray diffraction. Some fundamental data such as valance electron plasma energy, Penn gap, Fermi energy and electronic polarizability of the grown crystal were calculated. Microhardness investigations are conducted on the grown crystals. Mechanical behaviour was analyzed using Vicker’s microhardness test. Microhardness studies revealed that the hardness of the grown crystal decrease with an increase in load. Meyer’s index number n was calculated and found that the material belongs to hard material category .The dielectric constant measurements are carried out and the nature of variation of dielectric constant and dielectric loss in the frequency range of 50 Hz to 5 MHz is studied and reported.
