The gamma-glycine crystals are the efficient tools for today’s optoelectronic and photonic device fabrication as well as for NLO applications. A novel gamma-glycine (GG) crystal was grown by adapting conventional slow evaporation method at room temperature by using aqueous solution of cerous chloride. XRD studies were performed for grown crystal to identify the crystal structure. Functional groups are confirmed by the FTIR analysis and the optical parameters for the grown gamma-glycine crystal are found by recording UV- Vis spectrum. Hardness parameters were found out by Vickers microhardness testing. The elemental analysis for the GG crystal is confirmed by EDAX spectrum. The TG/DTA analysis was carried out for the sample to check the thermal stability. The nonlinear optical activity is confirmed by Second Harmonic Generation (SHG) analysis. The antibacterial activity analysis, cyclic voltammetric and impedance studies of the sample were also carried out and the results are discussed.
