Many attempts have been made to grow different derivative crystals of glycine. However, the title compound was not investigated thoroughly to understand the usability of the crystal for its device application. In the present investigation, using slow evaporation solution growth technique, single crystals of glycine have been grown in the presence of potassium iodide. Detailed investigations were made on structural and thermal properties of the grown crystals. Structural analysis was carried out by X-ray diffraction method, Fourier Transform Infrared, FT-Raman and Nuclear Magnetic Resonance spectral methods to conform the grown crystals. Thermal stability of the grown crystals was studied by Thermogravimetric (TG) and Differential Thermal analysis (DTA) and it was found that the crystal is stable up to 113°C. UV-Vis spectral analysis has been carried out and the crystal has not any significant absorbance in the entire visible region. Dielectric studies for the grown samples have also been studied. Nonlinear optical property has been confirmed by Kurtz powder technique and found that the grown crystal has nearly fifty percentage of SHG efficiency as that of standard KDP sample. The observed properties have confirmed that the grown crystal is suitable for nonlinear optical applications. Copyright © 2017 VBRI Press.
