Abstract

Single crystals of cadmium thiourea bromide (CTB), a novel semiorganic nonlinear optical material were grown from aqueous solution by slow evaporation method. Powder X-ray diffraction pattern and FT IR spectrum analysis confirmed the formation of crystal. CTB has good optical transmission in the entire visible region, which is an essential requirement for a nonlinear crystal. Fluorescence spectra analysis was carried out on the crystal. The optical second harmonic generation conversion efficiency of CTB was determined using Kurtz powder technique. The magnetic property of the crystal was investigated..
