Optical, thermal, mechanical and dielectric studies of L Alaine Potassium iodide single crystal by conventional solution growthtechnique

Abstract

L Alaine Pottassium (AL) single crystal was successfully grown using slow evaporation solution growth technique.The lattice parameter and crystal system was identified grown crystal from the powder X-ray diffraction (PXRD) measurement. The absorbance optical transmittance and optical band gap of grown crystal were identified using UV-Vis-NIR studies and the cut off wavelength is 234 nm. The optical band gap of the crystal was calculated, and it is 4.8ev. The dielectric constant and dielectric loss was measured in the room temperature for grown AL single crystal. Vickers microhardness investigationwas done to recognize the mechanical stability of the grown crystal.Fluorescence was analysis and it is possesses the blue emission the grown crystal.
