Effect of Glycine Doping in Potassium Hydrogen Phthalate (KHP) Crystals on Structural and Optical Properties


Article Preview

Influence of Glycine dopant in KHP single crystals have been investigated by slow evaporation solution growth technique. Concentration of Glycine in the KHP crystal was optimized and subjected to various spectral studies. Powder X-ray diffraction study reveals the orthorhombic structure of the grown pure and doped KHP crystals. The chemical components present in the crystals were confirmed with the help of FTIR spectrum. The enhancement of optical transparency in the doped KHP crystal was verified by UV-visible spectrum. The refractive indices along b-axis of the grown crystals were measured with Metricon-prism coupler instrument. The emission of green light confirms the SHG properties of the grown crystals.
