Studies of Glycine Guanidine Nitrate single crystals In the Aqueous Solution of α-Glycine and Guanidine Nitrate.

The field of nonlinear optics became practically a reality after the invention of laser. High Performance electro-optic switching elements for telecommunications and optical information processing are based on materials with high nonlinear optical (NLO) properties. The development and encroachment of high technology, from transportation, computation to information is based on the availability of materials in the form of single crystals. An semi organic nonlinear optical single crystal of Glycine Guanidine Nitrate (GLGN) has been grown by the aqueous solution of α -Glycine and Guanidine Nitrate by slow evaporation of the saturated solution at room temperature. Single crystal of (GLGN), an semi organic nonlinear optical (NLO) material, has been grown by slow solvent evaporation technique. Good optical quality single crystals with dimension up to 31 × 30 × 7 mm 3 are obtained. Single crystal X-ray diffraction (XRD) studies revealed the presence of monoclinic structure with space group. The crystals are characterized by optical absorption spectrum, FTIR and X-ray diffraction studies The mechanical and Differential thermal analysis (DTA) and thermo gravimetric analysis (TGA) study of the grown crystals are also investigated.
