Abstract
A non linear optical material Barium Calcium Borate (BCB) has been successfully grown from an aqueous solution by solution growth slow evaporation technique. The structure, composition and lattice parameter of grown crystal was determined by single crystal X-ray diffraction analysis. The observed infrared bands were assigned and peaks show that inorganic molecules with small amount of water molecules present in the crystal. UV - Vis - NIR shows optical band gap (4.85Â eV) is higher than other borate family crystals. NLO second harmonic efficiency was three by fourth times of KDP. Dielectric behaviour of the grown crystal reveals that for the grown crystal has higher dielectric constant (É>4500) in low frequencies at different temperatures and its activation energy (4.6Â eV @100 Hz, and 4.9Â eV @1 kHz) is increasing with respect to frequencies.
