Remarkable Effect of Alkali Metal Doping on the Properties of Potassium Hydrogen Phthalate Single Crystals for Optoelectronic and Nonlinear Optical Applications

Authors(2) :-S. Shek Dhavud, J. Thomas Joseph Prakash

This present investigation reports the impact of alkali metal, for example, Cesium (Cs) doping on the properties of potassium hydrogen phthalate (KHP) crystals were grown by means of slow evaporation solution growth technique. The XRD and FT-IR analyses imply that the crystal undergoes extensive stress because of doping. The decrease in the peak intensity for the particular plane of (130) observed in powder XRD for Cs doped crystal and slight modifications in vibrational frequencies show minor structural variations. The optical examinations were investigated by UV-Vis-NIR analysis and show high optical transparency in the doped sample. The photoluminescence analysis of the grown crystals was investigated. Surface morphological changes owing to doping are ascertained by SEM and addition of the Cs dopant into KHP crystal lattice was well affirmed by energy dispersive X-ray spectroscopy (EDAX). TG/DTA examination reveals the purity of the materials and no decomposition is seen up to the melting point. The remarkable enhancement in mechanical strength was ascertained owing to doping by Vickerís microhardness test. Itís observed that the doping with the low concentration of alkali metal facilitates nonlinearity and enhances the second harmonic generation (SHG) efficiency to a noteworthy extent.
