Abstract

L-Histidinium Maleate was synthesized and subsequently good quality single crystals were grown from aqueous solution by slow cooling technique. The grown crystals were subjected to powder X-ray diffraction to confirm the crystallinity. FTRaman spectra revealed the presence of various functional groups. 13C NMR analysis confirmed the formation of structure in the title compound. The optical properties of the grown crystals were analyzed by UV-Vis-NIR spectrum. The optical reflectance and extinction coefficient were also calculated for this crystal. The refractive index of the crystal was determined by prism coupling technique. Photoluminescence studies revealed that the material emitted violet emission. Vicker’s microhardness studies were carried out to study the mechanical property of the grown crystal. The second harmonic generation of the material was investigated by Kurtz-Perry technique, and the efficiency was estimated to be higher than that of KDP..
