Crystal Growth and Characterization of an Efficient Nonlinear Optical Material: γ-Glycine Crystal

In an aqueous solution of ferrous chloride, gamma - Glycine Crystal (gamma-GC), an efficient nonlinear optical (NLO) material, was created. AR grade glycine and ferrous chloride in a molar ratio of 1: 0.5 were employed to grow the title sample. The lattice properties of gamma-GC were determined using a single crystal X-ray diffraction method. High transmittance in the visible area and a UV-visible spectrum make gamma-GC excellent for optical applications. Using a Nd:YAG laser, the produced crystal's LDT value was ascertained. The crystal's hardness was assessed using the Vickers test, and other mechanical properties were determined. The electrical properties of gamma-GC were examined by measuring the dielectric constant and dielectric loss at various frequencies, and temperatures. Using TG/DTA tests to gauge the sample's thermal stability, the functional groups of the gamma-GC were identified by FTIR analysis. The material also underwent SHG and LDT testing.
