Growth and characterization of Imidazole Potassium Chloride – A semiorganic NLO Crystal

A new semiorganic nonlinear optical single crystal of Imidazole Potassium Chloride (IPC) has been grown successfully by slow evaporation method. Colourless, transparent IPC crystal of dimension 5 x 5 x 2 mm has been grown within a period of 21 days. The grown crystal was subjected to single crystal X-ray diffraction (XRD) analysis to determine the lattice parameters. The powder X-ray diffraction pattern of the grown crystal has been indexed. The presence of functional groups in the grown crystal was confirmed by fourier transform infrared spectroscopy (FTIR) analysis. The optical transmission property of the grown crystal was analysed using UV-VisNIR spectral analysis. The mechanical strength of the crystal was found out using Vickers microhardness test. The second harmonic generation (SHG) has been tested using Kurtz powder technique.
