“…Other advantages of these materials are their high flexibility in terms of molecular structure, their comparatively high optical damage threshold, low cost and their short response time to optical excitation (Boomadevi et al, 2004). The salts of weak carboxylic acid (maleic acid) with amino acids, viz., L-alaninium maleate (Natarajan et al, 2006) and L-arginine maleate were synthesized and reported recently as good NLO materials. Thus, the L-Alaninium maleate LAMA an aromatic organic compound is another such example to create interest in the study to evolve its optical characterization.…”

The innovation, with an eye for application, has been the key to successful crystal harvesting. It is realized that crystalline material is intrinsically applied and basic research in this area needs to be directed and motivated by specific applications in technology. Combination of aminoacids with organic materials gets increased efficiency made this study of optical characterization of l-alaninium maleate-a novel organic NLO crystal. The single crystals are grown by slow evaporation technique by mixing L-Alanine with maleic acid in the ratio 1:0.25, 1:0.5, 1:0.75, 1:1. Single crystal X-ray diffraction study is compared with powder X-ray diffraction study. The FTIR spectrum is drawn for the crystals and their functional groups were determined. The UV-Vis-NIR spectrum shows less optical absorption in the entire visible region. The band gap energy of the crystals were calculated. Non-Linear optical efficiency was evaluated by Kurtz and Perry powder technique using Q-switched Nd-YAG laser.

“…The salts of basic amino acid L-histidine added much interest as a promising nonlinear optical material after the works of Marcy et al, which reports that the nonlinearity of L-histidine tetraflouroborate is much higher than that of potassium dihydrogen phosphate [6]. Maleic acid, basically a dicarboxylic acid with large π-conjugation has attracted a great deal of attention [7]. On the basis of earlier reports on L-histidine salts, we have successfully grown monoclinic form of L-histidinium maleate (LHM), a new organic compound.…”

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.

“…Due to its basic nature L-histidine forms a number of salts with different organic and inorganic acids which have shown NLO properties. Maleic acid, basically a dicarboxylic acid with large π-conjugation has attracted a great deal of attention [9]. Based on the previous reports of L-histidine salts and their NLO properties, we have successfully synthesized L-histidinium maleate, a new analog of L-histidine salt.…”
