Abstract
The organic crystals with abundance of donor-acceptor moieties readily facilitate the mechanism of charge transfer which aids for grooming the nonlinear optical (NLO) effects and hence core investigation on glycine crystal is deliberately needed for visualizing its compatibility for frequency conversion device applications. In this communication the gamma glycine (GG) crystal has been firstly grown in presence of salicylic acid and priority is given to explore its optical properties. The structural parameters and space group of GG crystal has been confirmed by single crystal X-ray diffraction analysis. The qualitative analysis of GG crystal has been performed by means of fourier transform infrared spectroscopy. The color centered luminescence emission profile of GG crystal has been assessed by means of photoluminescence study. The UV-visible spectral analysis has been employed within 200-1100 nm to examine the optical transparency of GG crystal. The linear optical parameters of GG crystal has been evaluated using the transmittance data. The large enhancement in second harmonic generation (SHG) efficiency of GG crystal with reference to KDP and ADP crystal has been confirmed by Kurtz-Perry test. The competency of GG crystal for NLO device application has been proposed in vision of obtained results. (C) 2018 Elsevier B.V. All rights reserved.
