摘要：
A new nonlinear optical crystal urea thiourea cadmium sulfate (UTCS) has been grown by slow evaporation technique in equimolar ratio. The grown crystals were characterized by single crystal X-ray diffraction analysis which reveals that sample crystallizes in triclinic system with non-centrosymmetric space group P1. The powder XRD pattern revealed the formation of UTCS compound. High-resolution-X-ray diffraction analysis was carried out to study the crystalline perfection of the sample. Functional groups of the grown crystal were identified by FT-IR studies. Thermo gravimetric and differential thermal analyses were employed to understand the thermal and physio-chemical stability of the synthesized compound. UV–Vis–NIR spectrum revealed the transmission properties of the crystal specimen. The SHG efficiency has been tested by the Kurtz powder technique using Nd: YAG laser and found to be about 0.82 times in comparison with standard KDP crystals.
