Semi-organic nonlinear optical Tris(thiourea) cadmium sulphate (TTCS) single crystals were grown by slow evaporation method. The crystal system and cell parameter of the grown crystal were identified by powder X-ray diffraction study. By this study the dislocation density and strain values of the lattice were estimated. The mechanical property of the grown crystal was examined by using Vickers micro hardness test. The functional groups present in the grown crystals were ascertained using FTIR and FT-RAMAN spectroscopic analysis. Chemical etching studies were made on the TTCS crystal using water as an etchant. The dark and photocurrent property of the crystal was estimated by using photoconductivity study.
