Abstract
Single crystals of γ-glycine were grown by solvent evaporation method from a mixture of aqueous solutions of glycine and ammonium carbonate at ambient temperature for the first time. Powder XRD, CHN analysis, Differential scanning calorimetry analysis, Fourier transform infrared spectroscopic techniques were employed to characterize the crystal. The lattice parameters were calculated and they agree well with the reported values. The UV cut off of γ-glycine is below 300 nm and has a wide transparency window, which is suitable for second harmonic generation of laser in the green region. Nonlinear optical property of γ-glycine crystal were studied using Q switched Nd: YAG laser. The second harmonic generation conversion efficiency of γ-glycine is 1.85 times that of KDP.
