Growth and Characterization Studies on Nicotinic Acid Doped Kdp Crystals

Abstract

In the present work the growth of potassium dihydrogen phosphate crystal doped with nicotinic acid at various concentrations is reported. KDP is a well -known optical material having different applications in electro-optics and laser technology. Nicotinic acid doped KDP crystal is grown using slow solvent evaporation technique. The doping of nicotinic acid at various concentrations was successively achieved in KDP crystal and confirmed by Fourier transform infrared spectroscopy analysis. The modification of optical transmittance and other optical constants of KDP crystal due to the doping of nicotinic acid have been investigated by means of UV-visible spectral analysis. The dielectric behavior of the sample has been studied. The variation of the dielectric loss with frequency of the applied field is reported.
