SYNTHESIS, GROWTH AND CHARACTERIZATION OF L-VALINE ZINC HYDROCHLORIDE — A NOVEL SEMI-ORGANIC NONLINEAR OPTICAL SINGLE CRYSTAL

Abstract

Single crystals of L-valine zinc hydrochloride (LVZHCl), a novel semi-organic nonlinear optical material were synthesized and grown from aqueous solution by slow evaporation method at room temperature. The cell parameters of LVZHCl had been determined using single crystal X-ray diffraction technique. The linear and non-linear optical properties of the crystals were studied by Fourier Transform Infrared, Ultraviolet Visible Near infrared, ac impedance, laser damage threshold, and second harmonic generation analysis. The thermal stability of the crystals was assessed by Differential thermal-Thermogravimetric analysis. The crystallinity and mechanical properties of the crystals were studied by Dielectric behavior and Vickers microhardness test.
