Abstract—L-histidinium maleate, a new amino acid organic nonlinear optical material has been successfully grown from aqueous solution by slow solvent evaporation method. The grown crystal was subjected to single crystal X-ray diffraction study for the identification of the structural arrangement. The chemical composition of the grown crystal was estimated by Energy dispersive X-ray analysis. In order to confirm the molecular structure of the grown crystal, FT-NMR spectral analysis was carried out. The percentage of optical transmittance by the grown crystal was ascertained by UV–visible spectral study. The nonlinear optical property of the grown material was identified by the powder technique of Kurtz and Perry. The HR-SEM analysis shows the surface morphology of the grown crystal. The thermal stability of the grown crystal was found by differential thermal analysis.

Index Terms—NLO, XRD, EDAX, FT-NMR, HR-SEM.
