Synthesis and Spectroscopic Characterization of Pure and l-Arginine Doped KDP Crystals

Abstract

Optically good quality single crystals of pure and l-arginine-doped KDP crystals were grown by a slow evaporation method. The grown crystals were subjected to optical and dielectric studies. The unit cell parameters were calculated by X-ray diffraction. The UV-Vis spectrum shows the transmitting ability of the crystals in the entire visible region and transmittance percentage is increased for the doped KDP crystals. The presence of the functional groups has been identified by FT-IR spectrum. Hence, l-arginine doped KDP crystals are found to be more beneficial from an application point of view as compared to pure KDP crystals. From Microhardness test it has been observed that the addition of organic additives improves the mechanical strength of the crystal.
