Single crystals of γ-glycine were grown by submerged seed solution method, hanging seed solution growth method and solvent evaporation method. Powder X-ray diffraction (XRD) studies were carried out to confirm the crystalline gamma phase and to find out the lattice parameters of the grown crystals. The presence of various functional groups was determined by Fourier transform infrared (FTIR) spectroscopic analysis. Thermal analysis was carried out to study the thermal stability and phase transition of the grown crystals. The Vickers microhardness test was performed. UV-visible transmittance spectra showed wide transparency window in visible and near infrared (NIR) region. The second harmonic generation (SHG) relative efficiency of the grown crystals was measured by Kurtz and Perry powder technique using Nd: YAG laser. Key words: Growth from solutions, X-ray diffraction, Fourier transform infrared (FTIR), optical property, microhardness, second harmonic generation.
