Influence of l-alanine doping on zinc (TRIS) thiourea sulphate (ZTS) single crystals

Abstract

ZTS has been grown using a slow evaporation technique at ambient temperature, and the L-alaninedoped ZTS was likewise prepared. Powder X-ray diffraction (XRD), Fourier Transform Infrared spectroscopy (FTIR) and Vickers's micro hardness test have all been used to analyse growing crystals.Both pure ZTS and L-Alanine-doped ZTS crystals have an orthorhombic structure. L-alanine doped ZTS had greater second harmonic generation (SHG) conversion e ciency. L-alanine doped ZTS crystals had a higher hardness than a pure ZTS sample. UV spectral analysis indicates that both crystals have excellent UV and visible transmission. Doping with L-alanine resulted in an increase in the melting point of the pure ZTS crystal.

Investigation of optical, Thermal studies on semi organic Nonlinear Optical Single Crystal Thiosemicarbazide Potassium Bromide (TSCPB) for Optoelectronic devices applications

“…The thiosemicarbazide molecule is centrosymmetric by nature, but when combined with inorganic compounds, complexes are produced that are noncentrosymmetric [10,11]. In this study, potassium bromide is attached to thiosemicarbazide to generate a novel semi organic (metal-organic) compound in this series [12][13][14][15]. Many thiosemicarbazide associated compounds, such as Thiosemicarbazide potassium chloride (TSCPC), thiosemicarbazide cadmium chloride monohydrate (TSCCCM), and thiosemicarbazide lithium chlorides [TSLC], have been identi ed as good semi-organic nonlinear optical materials.…”
