Thermal and Optical Properties of Glycine Crystals with Additives of Nitrates
Semi-organic crystals of Glycine Sodium nitrate Calcium nitrate (GSC) with two different molar ratios were grown using slow evaporation technique. Crystals of size 22 × 16 mm were obtained within time period of 3-4 weeks at ambient temperature. The compositional study and purity of the crystals were determined using Energy Dispersive X-ray Analysis (EDAX) and CHN Analyzer. Surface of the crystals was studied at micrometer scale with optical microscopy. These crystals were characterized by powder X-ray diffraction and indexing of diffraction pattern was done based on monoclinic system. We also studied thermal properties of these crystals using TGA/DTA/DTG analysis. From UV-Vis spectra we could observe wide transparency window from these crystals in the visible region, which can be useful for opto-electronic applications.
