Novel report on γ-glycine crystal yielding high second harmonic generation efficiency

Abstract

Present investigation very firstly reports the growth of γ-glycine crystal from aqueous solution containing cesium chloride. The crystallographic data of γ-glycine crystal has been experimentally determined by means of single crystal X-ray diffraction (XRD) technique. The powder XRD technique has been employed to examine the crystalline nature and structural parameters of grown crystal. The element detection has been achieved by means of energy dispersive spectroscopic technique. The color centered luminescence behavior of γ-glycine crystal has been analyzed in the range of 300–700 nm. The UV–visible study has been carried out within 200–1100 nm to determine the optical transparency and optical band gap of grown crystal. The second harmonic generation (SHG) efficiency of γ-glycine crystal has been determined by means of Kurtz-Perry test and the SHG efficiency is found to be 5.06 times higher than standard potassium dihydrogen orthophosphate crystal material. The dielectric parameters of grown crystal have been evaluated at different temperature and frequencies. The grown crystal has been subjected to differential thermal analysis to determine the melting point of γ-glycine crystal.
