Abstract: A highly efficient nonlinear optical single crystals of tetrathiourea mercury (II) tetrathiocyanato zinc(II), Hg(N2H4CS )4Zn(SCN)4, (TMTZ) were conveniently grown from mixture solvent of ethanol–water by slow evaporation technique. The grown crystals exhibited needle-shaped morphology. The cell parameters of TMTZ single crystals were determined by single-crystal X-ray diffraction. The grown crystals were subjected to optical characterization by FT-IR, FT-Raman and UV–Vis–NIR techniques. The dielectric study of TMTZ showed low dielectric loss in the high-frequency region. The photoconductivity studies confirm that the TMTZ crystal has negative photoconducting nature. [Copyright &y& Elsevier] |
