Growth and Physical Properties of Pure and Potassium Iodide Doped Zinc Tris Thiourea Sulphate Single Crystals
Journal Title: International Journal of engineering Research and Applications - Year 2017, Vol 7, Issue 8
Abstract
Nonlinear Optical Single crystals of undoped and potassium iodide doped zinc tris thiourea sulphate (ZTS) were grown from aqueous solutions by slow evaporation method at ambient conditions. The dielectric studies revealed that the dielectric constant is relatively higher in the low frequency region and lower (~ 226 and ~ 221) in the higher frequency region. The information on the quality of samples and smoothness of the crystal surface without having any defects are provided by the scanning electron microscopy results. The grown crystals act as window in the visible regions which is confirmed by PL studies. The estimated energy band gap of the pure and doped crystals is 2.67 eV and 2.69 eV. The values of elemental content of the grown crystals were measured by EDAX technique. The results suggest that the material is highly suitable for the fabrication of Photonic devices.
