EFFECT OF L-THREONINE ON THE OPTICAL PROPERTIES OF (TRIS) THIOUREA ZINC SULPHATE (TTZS) SINGLE CRYSTAL

The growth of L-Threonine doped Zinc (tris) Thiourea Sulfate single crystal from aqueous solution by low temperature solution growth has been reported in the present investigation. The 1, 2 and 3 mole% L-Threonine was doped in saturated TTZS solution. The effect of L- Threonine on SHG property was studied by Kurtz and Perry powder SHG test. The higher enhancement in SHG efficiency was observed at 1mole% LThreonine doped TTZS. Hence, the growth 1mole% L- Threonine doped TTZS was carried. The grown crystal was characterized by single crystal X-ray analysis, FT-IR, UV-visible spectroscopy and thermal study by TGA and DSC analysis.
