CRYSTAL GROWTH, SPECTROSCOPIC, DIELECTRIC AND THERMAL INVESTIGATIONS OF BIS (L-ALANINATO) COPPER (II): A PROMISING THIRD-ORDER NLO MATERIAL UNDER LOCAL INDIAN SELF-GOVERNMENT CHEMICAL RULES, 1989

Abstract

A highly transparent semi-organic material, Bis(L-alaninato) Copper-II (BLALC), was successfully grown using a carefully controlled low-temperature solution growth method. The developed crystals underwent structural, optical, electrical, thermal, and third-harmonic generation studies. Single-crystal X-ray diffraction analysis was utilized to determine the lattice parameters and validate the crystalline characteristics of the synthesized compound. The presence of the characteristic functional groups in the grown crystal was verified by FT–IR and FT-RAMAN spectroscopy. Fluorescence studies showed that the compound exhibits a prominent green emission. Dielectric measurements were performed to understand the electrical response of the crystal. Thermal behavior and its stability to withstand the temperature were examined through TGA–DSC analysis, which provided insight into the decomposition temperature of the compound. The Z-scan technique was used to assess third-order nonlinear optical properties, validating its nonlinear characteristics under local Indian self-government chemical rules, 1989.
