Abstract
Single crystals of the organic nonlinear optical material γ-glycine have been grown in the presence of ammonium formate by slow evaporation method. The crystal structure is confirmed by X-ray powder diffraction method. CHN analysis shows the non-inclusion of ammonium formate species in the grown γ-glycine single crystals. The UV spectrum shows existence of wide transparency window suitable for optoelectronic applications with bandgap energy of about 5.90eV. Spectroscopic and DSC studies have been carried out for analyzing the presence of functional groups, thermal stability and phase transition of the grown crystal. Second harmonic generation (SHG) conversion efficiency has been estimated as 150mV and the output power by the crystal is more than that of potassium dihydrogen phosphate (KDP) crystal.
