Abstract

Abstract: Nonlinear optical crystals of L-Lysine adipate were grown by liquid diffusion method at room temperature. The lattice parameters were determined by single crystal X-ray diffraction analysis. Fourier Transform Infrared and Raman spectral studies were carried out to confirm functional groups present in the crystal. Optical property of crystal was examined by UV–vis–NIR studies. Molecular structure of grown crystal was established using 1 H NMR and 13 C NMR studies. Thermal stability and decomposition were analyzed using Thermo Gravimetric and Differential Thermal analysis. Second harmonic generation efficiency of crystal was determined by Kurtz Perry powder technique. Highlights: L-Lysine adipate crystals were grown from Liquid diffusion method. The material possesses a wide transparent range. The spectroscopic analysis of the material was made using FTIR and FT Raman spectra The crystal exhibits good nonlinear optical property. Crystal have better thermal property and can be used for NLO application upto 205 °C.
