RESUMEN
<100> directed single crystals of zinc (tris) thiourea sulphate, a semi-organic compound, have been grown at an average growth rate of 2mm per day by Sankaranarayanan-Ramasamy (SR) method. Transparent ZTS crystal of size 70mm length and 15mm diameter was grown. The growth conditions have been optimized. Chemical etching, Vickers microhardness, UV-Vis NIR, dielectric constant and dielectric loss analysis were made on conventional and SR method grown ZTS crystals. Thermo gravimetric and differential thermal analysis was carried out to determine the thermal properties of the grown crystal. The NLO efficiency of the crystal has been confirmed using the Kurtz powder technique. The comparative study indicates that the crystal quality of unidirectional grown ZTS crystal is better compared to conventional slow evaporation method grown crystal.
