Synthesis, growth and characterization of a semiorganic nonlinear optical material: l-Threonine cadmium chloride single crystals

Abstract

A semiorganic nonlinear optical single crystal was grown from aqueous solution by slow evaporation method at room temperature. The characterization of the crystal was made using single crystal and powder X-ray diffraction analysis and it was found to be the LTCC crystallized in orthorhombic crystal system with noncentro symmetric space group. The UV–vis spectroscopic study reveals that the crystal has good optical transparency and lower cut off wavelength was found to be 332nm. The presence of functional groups was identified by FTIR spectra. The percentage of carbon, hydrogen and nitrogen was analyzed by elemental analysis. The microhardness was tested using Vicker's microhardness tester. The nonlinear optical property was confirmed by Kurtz–Perry powder technique and it was found to be 0.7 times higher than pure KDP crystal.
