Abstract
Semi-organic nonlinear optical crystal of urea barium chloride has been grown from aqueous solution by slow evaporation technique at room temperature. EDAX analysis was carried out to identify the constituent elements present in the as grown crystal sample. The grown crystals were characterized by using powder X-ray diffraction analysis. The grown crystal was subjected to single-crystal X-ray diffraction analysis to find the lattice parameter and system of the crystal. The vibrational frequencies of various functional groups were confirmed by Fourier transform infrared spectroscopy (FTIR) analysis. The UV–vis–NIR spectrum of the crystal shows the lower cut-off wavelength at 320 nm. The dielectric properties were studied at room temperature. The optical behavior, including second harmonic generation (SHG), was investigated to study its NLO property and compared with KDP..
