Growth, Optical, Dielectric and Hardness Studies of an Organic Nonlinear Optical Picolinium Maleate Single Crystal

Abstract

Picolinium maleate (PM), a novel organic compound has been synthesised and bulk crystal has been grown from the aqueous solution by slow evaporation technique. The structure of the grown crystal was elucidated by using single crystal XRD analysis and powder XRD pattern further confirmed the crystallinity of the grown PM crystal. The presence of functional groups in PM were identified by FTIR spectral analysis. UV-Vis spectral studies revealed that PM crystals are transparent in the wavelength region 327–1100 nm. The laser damage threshold value of PM crystal was measured using Nd:YAG laser. The second harmonic conversion property was studied by Kurtz and Perry powder technique.
