Growth, Optical, Thermal, Mechanical and Etching Studies on NLO Active Pure and L-Alanine Doped Single Crystals of Bis-Thiourea Cadmium Chloride

Abstract

The pure semiorganic nonlinear optical material Bis thiourea cadmium chloride (BTCC) and L-Alanine doped BTCC, were grown by slow evaporation technique at room temperature. The crystals obtained by the above technique were subjected to different characterization analysis. Unit cell parameters were evaluated by single crystal X-ray diffraction technique. The functional groups and optical behaviour of the crystals were identified from FTIR and UV-vis spectrum analysis. Micro hardness and thermal studies were also carried out on the samples respectively. The SHG efficiency of the grown crystals was measured through NLO studies
