Synthesis, Growth and Characterization of Semi Organic Nonlinear Optical Maleic Added Lithium Sulphate Monohydrate Crystal

Abstract

The present study aims at exploring the enhancing effects of maleic acid on the lithium sulphate monohydrate crystals grown by slow evaporation method. The powder XRD analysis confirm that the grown crystal belong to monoclinic structure with space group P21. The Fourier transform infrared spectroscopy study revealed the inclusion of the maleic acid into the crystal. The optical transmittance study was used to estimate the lower cut off frequency and optical band gap. The Vicker's microhardness test was employed to find out the mechanical strength of the crystal.
