Investigation about nonlinear optics and antibacterial activity of pyrrolidine-2-carboxylic acid cadmium chloride hydrate single crystal

This work intends to investigate the superior properties of Pyrrolidine-2-carboxylic acid Cadmium Chloride Hydrate (PCCH) that was grown by the slow evaporation technique at room temperature. The crystalline nature of PCCH was found by powder X-ray diffraction analysis. The optical behaviour of the grown crystal was unveiled by using UV-vis-NIR. The refractive index of the crystal was measured experimentally using Metricon prism coupler for the first time. The z-scan measurement was taken to explore the third harmonic generation efficiency of the grown crystal for the first time. The structural imperfections were analyzed by performing the etching studies on the grown crystal. The first attempt of antibacterial activity of this crystal was carried at different concentrations (25, 50, 75 and 100 μg/mL) in-vitro against Staphylococcus epidermis (G + Ve); Escherichia coli, Vibrio cholera (G-Ve) bacteria. These studies established that PCCH crystals might find useful applications in the field of biomedical and nonlinear optics.
