Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy

l-Alanine dl-mandelic acid hemihydrate (LADLMAH) an organic nonlinear optical chromophore crystal was synthesized using water as solvent and the crystals were grown by a slow solvent evaporation method. The single crystal X-ray diffraction study reveals that the crystals possess to triclinic system with acentric space group P1. The coordination of different moieties present in the compound and molecular structure were elucidated by vibrational and NMR spectroscopic studies. The lower cut-off wavelength is observed down to 258 nm and direct optical band gap was calculated as 5.20 eV. Second harmonic generation was confirmed by Kurtz–Perry powder method. Discrete thermodynamic properties were carried out by TG–DTA techniques. A multiple shot laser technique was adopted to investigate the surface laser damage of the crystal. The microhardness test was carried out employing one of the as-grown hard crystals and there by hardness number (Hv) and Meyer’s index (n) were assessed. The dielectric behaviour of the grown crystal was studied for different temperatures at different frequencies. The third-order optical nonlinearity parameters of LADLMAH were investigated in detail using a Z-scan technique with Nd:YAG laser at 532 nm. © 2018, Springer Science+Business Media, LLC, part of Springer Nature.

Growth and characterization of a nonlinear optical material: l-alanine dl-mandelic acid hemihydrate

Growth and spectroscopic investigation of a new crystal for NLO applications: C10H20KN5O9

A new nonlinear optical material, l-alanine acetate (l-AlAc) has been synthesized. Single crystals of l-AlAc have been grown by the slow cooling method. Bulk crystals have been grown with a solution pH of 3.0. The grown crystals were subjected to various characterization studies such as chemical etching, dielectric measurement, FTIR analysis, UV-visible spectrum and powder SHG test. The structure of the crystal was confirmed by single-crystal X-ray diffraction analysis. l-AlAc crystals exhibit better thermal and mechanical stability with improved optical properties. © 2004 Elsevier B.V.
