摘要：
A new semi-organic nonlinear optical material of tris thiourea magnesium zinc sulphate (TTMZS) crystal was synthesized and grown from aqueous solution by slow evaporation solution growth technique. Single crystal X-ray diffraction (XRD) study was carried out to identify the lattice parameters. Various diffracting planes of the grown crystal were identified from the powder X-ray diffraction study. EDAX analysis confirms the presence of metals in the TTMZS crystal. SEM shows the good surface morphology of the grown crystal. Fourier-transform infrared (FT-IR) studies confirm the presence of various functional groups present in the as grown crystal. The transmission spectrum shows that the lower cutoff wavelength lies around 280 nm. The nonlinear optical (NLO) property of the grown crystal has been studied by Kurtz powder second harmonic generation (SHG) test. The thermal analysis confirmed that the crystal is stable up to 248.46 degrees C. The mechanical behavior has been assessed by Vicker's microhardness indenter. Also dielectric measurements and photo conducting measurements were carried on. (C) 2015 Elsevier GmbH. All rights reserved.
