Growth, Spectral, Optical and Thermal Studies of Rare Earth Neodymium(III)Nitrate Doped Tris Thiourea Zinc(II)Sulphate Single Crystals


Article Preview

Tristhiourea Zinc(II)sulphate (ZTS) and rare earth Neodymium(III)Nitrate doped Tristhiourea Zinc(II)sulphate compounds were synthesized and single crystals were grown from aqueous solution by slow evaporation technique. The cell parameters of the grown crystals were evaluated by single crystal X-ray diffraction studies and powder X-ray diffraction analysis further confirmed the crystalline nature of the grown crystals. The presence of functional groups in the grown crystals was confirmed by FTIR analysis. UV-Visible absorption spectra reveal the cutoff wavelengths of grown crystals. TGA/DTA thermal analyses revealed that the materials have good thermal stability. The incorporation of the impurity (Nd3+) entered into ZTS crystals was confirmed by SEM-EDX analysis. The microhardness studies on the grown crystal samples revealed that the hardness increases with applied load for all the grown crystals. From the values of work hardening coefficient, ZTS and Neodymium(III)Nitrate doped ZTS crystals were found to be soft category materials. The second harmonic signal from ZTS and Neodymium(III) Nitrate doped ZTS crystals were tested by Kurtz-Perry method using Nd:YAG laser.
