INVESTIGATION ON THE PHYSICOCHEMICAL PROPERTIES OF NONLINEAR OPTICAL SINGLE CRYSTAL: 2-NAPHTHALENOL
Abstract
Single crystals of 2-Naphthalenol (2N), new organic nonlinear optical (NLO) material, have been grown by slow evaporation solution growth technique at room temperature. The crystal system has been confirmed from the single crystal X-ray diffraction analysis. The functional groups were identified using FTIR spectroscopy. UV-vis-NIR spectrum showed absence of absorption in the wavelength region 400–1400 nm. The second harmonic generation efficiency is two times higher than that of standard potassium dihydrogen phosphate (KDP).
