Investigation of Structural, Spectral, Optical and Thermal properties in Grown Pure Bis Thiourea Zinc Acetate (BTZA)

The nonlinear optical single crystal of bisthiourea zinc acetate (BTZA) was grown successfully by slow evaporation technique using water as solvent at room temperature. The lattice parameters of the grown crystal were determined by X-ray diffraction studies. The quality of the grown crystal was examined by scanning electron microscopy (SEM).The optical transparency was determined by UV-visible and photoluminescence spectroscopy studies. The thermal behavior of the grown crystal was investigated by DTA and TGA analysis. The presence of functional group was studied using FTIR spectra. The second harmonic generation (SHG) of BTZA was confirmed the nonlinear property of the crystal by Kurtz powder technique.
