Synthesis, Crystal Growth and Characterization of Semi Organic NLO Materials: L-Valine Zinc Chloride as Optic Sensor

A good quality single crystals of L-Valine Zinc Chloride were grown by slow evaporation solution growth technique with different concentrations (0.25, 0.50, 0.75 and 1.0 mole).Single crystal X-ray diffraction technique reveals that the grown single crystals were crystallized in the monoclinic structure.Solid state parameters were calculated for the grown crystals. Kurtz powder technique was used to test the nonlinear optical (NLO) activity of the samples which are semiorganic in nature.The optical properties of the crystals were investigated by UV-Vis. absorption spectroscopy. The results revealed that, the wider bandgap and large transparency in the visible region along with higher polarizability of the grown crystals are highly useful in optoelectronic sensors.
