A semi organic non-linear optical crystal Urea Thiourea Sodium Sulphate (UTNS) has been grown by slow evaporation method at room temperature. The grown crystal was characterized by the presence of powder XRD technique. The presences of various functional groups of the crystal were identified by FT-IR analysis. Optical transmission property of the material was established by UV-Vis spectrum. Thermal studies (TG/DTA) confirm that the stability of the crystal is around at 230 °C. Surface Morphology of the grown crystal of UTNS was carried out by SEM.
