Abstract
An organic nonlinear optical single crystal of gamma glycine (GGLY) has been grown by
slow evaporation of the saturated solution at room temperature. Single crystal of gamma glycine
(GGLY), an organic nonlinear optical (NLO) material, has been grown by slow solvent evaporation
technique. Good optical quality single crystals with dimension up to 32 × 31 × 7 mm3 are obtained. The
crystals are characterized by optical absorption spectrum, FTIR and X-ray diffraction studies. The
dielectric response of the sample is studied as a function of frequency and temperature. The mechanical,
photoconductivity and ac/dc behavior and Differential thermal analysis (DTA) and thermo gravimetric
analysis (TGA) study of the grown crystals are also investigated.
