Glycine doped L-Alanine sodium sulphate single crystals for nonlinear optical applications

Abstract

ABSTRACT The optically good superiority of NLO transparent 2 mol % of glycine doped L-Alanine sodium sulphate (LASS) single crystals were effectively developed by slow evaporation method. The crystalline nature of LASS and GLASS crystals were confirmed via XRD pattern and the diffraction peaks were well-indexed in the standard values. The FT-IR and FT-NMR spectroscopy studies were qualitatively established by the existence of all the functional groups through their atomic configurations in the molecular structure too. From the UV-Visible optical absorbance studies, the value of bandgap was determined at 5.22 and 5.51 eV for LASS and GLASS crystals sensibly. The SHG proficiency for GLASS crystal was measured using Nd: YAG laser and the value found to be 1.09 times superior to that of standard KDP material. The good structural, optical, thermal and SHG efficiency outcomes specified that the GLASS crystals might be very beneficial for NLO device applications.
