Organic nonlinear optical (NLO) crystals of 2aminopyridinium salicylate have been grown by slowevaporation growth technique using acetone: water mixed as solvent. The crystal structure, lattice parameters andcrystalline perfection were confirmed by Single crystal and powder X-ray diffraction analyses. The functional groups andchemical composition of grown 2ASA crystal was confirmed by FTIR analysis. UV-Vis spectral study showed that growncrystal has high transparency (~82%) in the entire visible region and the cut off wavelength at 360 nm. PL spectral studyof grown 2ASA showed an intense emission peak at 362 nm for an excitation wavelength at 340nm. The SHG relativeefficiency of 2ASA crystal has been found 1.19 times higher than that of KDP. Thermal analysis reveals that 2ASA isthermally stable up to 150°C.
