Influence of Zn2+ ion on the organometallic l-alanine cadmium chloride single crystals

The single crystals of pure and zinc chloride-doped l-alanine cadmium chloride (LACC), an organometallic nonlinear optical material, are grown by a slow evaporation technique. The grown crystals were subjected to X-ray diffraction analysis, scanning electron microscopic study, and energy-dispersive analysis by X-ray and thermal studies. The second harmonic generation was confirmed by the Kurtz and Perry powder technique. The dielectric measurements were carried out for different frequencies at different temperatures. The second harmonic efficiency and dielectric constant increases significantly due to introduction of smaller ionic radii Zn²⁺ ion into the lattice of pure LACC crystal; so that the zinc chloride-doped LACC crystals are found to be potential material for nonlinear frequency conversion.
