ABSTRACT
In the current research, Zinc (tris)-thiourea sulfate (ZTTS), a metal-organic crystal, has been synthesized using the slow solvent evaporation technique. Powder-X-ray diffraction (PXRD) analysis, Fourier transform infrared (FT-IR) spectroscopy, UV-Vis spectroscopy, photoluminescence (PL) spectroscopy, and thermal, and second harmonic generation measurements have all been applied to describe the as-synthesized ZTTS crystals. The synthesized samples crystallized in an orthorhombic structure, based on XRD analysis. The functional groups of ZTTS samples were validated by FT-IR analysis. The extensive transparency of ZTTS over the UV-visible spectral region has been confirmed by UV-Vis analysis and the band gap has been estimated as 4.43 eV. The photoluminescence spectra exhibit a prominent emission peak around the wavelength of 484 nm and significant emission peaks at 444 and 513 nm with an excitation wavelength of 250 nm. The SHG test illustrates the creation of second harmonic signals from the ZTTS samples. The thermal response of the as-synthesized ZTTS was shown by the TG/DTA measurements. The results suggest that as-synthesized ZTTS crystals could be used as a possible nonlinear optical substance.
