Growth and Characterization of Disodium Hydrogen Orthophosphate (DSHP) Single Crystals

Abstract

Nonlinear optical materials are expected to be active elements for optical communication and optoelectronics. Because of their higher nonlinearity, these materials show the second order nonlinear optical effects. Among the nonlinear phenomena frequency doubling, frequency mixing, and electro-optic modulation are important in the field of optical image storage and optical communications. In the present work, disodium hydrogen orthophosphate single crystals have been grown from aqueous solutions by slow evaporation at room temperature. Good quality transparent crystals have been obtained. Electrical measurements at different temperatures and frequencies were carried out. The material of the grown crystals was confirmed by X-ray powder diffraction. The Fourier Transform Infrared (FTIR) spectrum of the grown crystals was also recorded. The results are reported.
