Effect of Cadmium sulphate on the Growth and Characterization of L Valine Crystal

By slow evaporation of a new semi organic nonlinear optical crystal and by synthesizing L-Valine cadmium sulphate good optical quality single crystals were grown. By powder X-ray diffraction studies, the growth conditions of the crystals are studied and the crystalline natures of grown crystals are confirmed. By using powdered XRD, FTIR, UV-Vis-NIR and DSC –TGA, the grown crystals was characterized. The high crystallinity of the grown crystal is shown by the sharp peaks from powdered XRD spectrum. By using FTIR spectroscopic technique the presence of various functional groups were confirmed. The UV-Vis-NIR spectrum is used to indicate that the crystal has very good absorption in the entire visible and near IR region spectrum indicates suitability of the material for NLO applications. By thermo gravimetric analysis, the stability of the thermal and mass loss has been estimated.
