Good quality single crystals of L-valine copper chloride were grown by slow evaporation solution growth technique with different concentrations (0.25, 0.50, 0.75 and 1.0 mol). Single-crystal X-ray diffraction technique reveals that the grown single crystals were crystallized in the monoclinic structure. Kurtz powder technique was used to test the nonlinear optical (NLO) activity of the samples which are semi-organic 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. The high transmittance and the low absorbance and reflectance of the material over a wide range of wavelength suggest that the material can be used as anti-reflection coating in solar thermal devices and nonlinear applications.

半有机NLO材料的合成,晶体生长和表征:L-缬氨酸氯化铜作为光电传感器

通过缓慢蒸发溶液生长技术,以不同的浓度(0.25、0.50、0.75和1.0 mol)生长了高质量的L-缬氨酸氯化铜单晶。单晶X射线衍射技术表明,生长的单晶以单斜晶结构结晶。使用Kurtz粉末技术测试了半有机样品的非线性光学(NLO)活性。晶体的光学性质通过紫外可见吸收光谱法进行了研究。结果表明,在可见光区域中较宽的带隙和较大的透明度以及所生长晶体的较高极化率在光电传感器中非常有用。
