Abstract

ingle crystal of an organic nonlinear optical (NLO) material, Picric acid , was grown by slow evaporation method. The structural perfection of the grown crystal was analyzed by X-ray diffraction measurements. UV-Visible-NIR spectral analysis was used to determine the optical constants and band gap of Picric crystal.FT-IR spectral analysis the presence the type of functional group. TGA showsthe good thermal stability of the material. The hardness measurement determines the mechanical stability of the Picric acid crystal.
