Abstract

Single crystals of hydroxyethylammonium picrate (C8H10N4O8; HEAP) have been grown for the first time by slow evaporation solution growth technique at room temperature, using ethanol as solvent. FT-IR and Raman spectra were recorded for HEAP at room temperature. The main vibrational bands related to NH3+ and CO- (picrate) groups, involved in charge transfer, are discussed. Second-order hyperpolarizability(gamma) for the single crystal was evaluated theoretically to be 3.48x10(-28) e.s.u. A Z-scan study of HEAP showed that the relative third-order nonlinear refractive index is -9.2x10(-5)cm(2)/W. The measured third-order nonlinear properties confirm the suitability of the crystal for optical limiting and switching applications.
