Abstract: Al2O3:Eu3+ nanophosphors were prepared by laser vaporization method in a flowing mixture of Ar/He and O2. Luminescence properties of Al2O3:Eu3+ nanophosphors are predominantly determined by Eu3+ ions red emission with inhomogeneously broadened bands in the region of 550-750 nm corresponding to 5D0 →7FJ transitions of Eu3+ (J = 0 - 4). Hypersensitive electric dipole transition 5D0 →7F2 dominates in the spectrum and is responsible for the red emission. The effect of crystallite size on luminescence properties of Al2O3:Eu3+ nanocrystals was observed. It was shown that the introduction of oxygen during the synthesis improves the luminescence performance. The obtained chromaticity coordinates and high absolute QY (~ 14%) indicate the possibility of using red nanophosphors based on Al2O3:Eu3+.
