With an aim to synthesize environmentally stable material possessing non- linear optical properties, we have grown Potassium Thiourea Dichromate (PTDC) and Copper Thiourea Sulphate (CTS) single crystals of good quality by inexpensive slow evaporation growth technique. The morphological analysis of grown crystal has been carried out to find the effect of dopant species on growth process. The XRD analysis of these crystals has been performed by powdered X-ray diffraction method which indicate the variations in lattice parameters and cell size to some extent with induction of metal salts in Thiourea ligand but without appreciably changing the crystal systems .FTIR and UV-Vis analysis of pure Thiourea,PTDC and CTS has been carried out to compare transmission and absorption abilities and to explore its suitability for NLO applications.
