Growth and characterization of noncentrosymmetric single crystals of l-Argininium-4-nitro Phenolate Monohydrate (LARP): A potential second order nonlinear optical material

A potential second order NLO material l-Argininium-4-nitro Phenolate Monohydrate (LARP) was grown by the slow evaporation technique. The grown organic NLO crystals were subjected to various studies such as single crystal XRD, UV-Visible spectrum, photoluminescence, Second Harmonic Generation (for various particle sizes) and laser damage threshold (LDT) studies. The LARP crystal belongs to orthorhombic system with noncentrosymmetric space group P212121. Piezoelectric charge coefficients of the grown crystal have been determined. The dielectric studies were performed at different temperatures and frequencies to analyze the electrical properties. The microhardness measurements were used to investigate the mechanical property of the grown crystal.
