Growth and Characterization of a New Nonlinear Optical Crystal: Bis Thiourea Zinc Chloride

Bis Thiourea Zinc Chloride (BTZC) a new semiorganic nonlinear optical material has been synthesized. The solubility studies have been carried out in the temperature range 30°- 55°C. Single crystals of BTZC have been grown by slow evaporation of saturated aqueous solution at room temperature. The lattice parameters of the grown crystals have been determined by single crystal X– ray diffraction technique. The UV-Vis-NIR transmittance spectrum has been recorded in the range 200 – 2000 nm. The FT-IR spectrum has been recorded in the range 400 – 4000 cm^-1 and the spectral bands have been compared with similar thiourea complexes.

Keywords: bis thiourea zinc chloride , FT-IR, nonlinear optical material, single crystal
