Spectroscopic Investigation on fundamental modes of pure and doped BTMC NLO single crystals

Author(s): Sethu Gunasekaran, Padmapriya Venkatesan, Govindarajulu Anand, Subramanian Kumaresan

Thiourea is potentially capable of forming coordinate bonds through both sulphur and nitrogen even though the extremely low basicity of the ligands militates against the formation of nitrogen-metal bonds. Both these possibilities will be reflected in the infrared spectra of the complexes. The centrosymmetric thiourea molecule when combined with inorganic salts yields non-centrosymmetric complexes, which has non linear optical properties. In the present study optically transparent crystals of Pure and doped BTMC crystals have been grown. The crystals are characterized by subjecting to Powder XRD, AAS, FTIR, UV and SHG tests are discussed and values tabulated.
