«Influence of Structural Disorder on the Luminescence Properties of Nanosize Eu\(^{2+}\)/3+-Doped Al\(_2\)O\(_3\)»
707–716 (2020)

PACS numbers: 61.05.cp, 68.37.Lp, 78.55.Hx, 78.67.Bf, 79.60.Ht, 81.07.Bc, 81.40.Tv

It is shown the possibility of preparation of nanosize (10Ц70 nm) Eu\(^{2+}\)-doped Al\(_2\)O\(_3\) by gas-disperse synthesis. By means of luminescent spectroscopy, it is found that some part of Eu ions is stabilized in the +2 oxidation state in the synthesis products and emits in the 360Ц550 nm range with a maximum at \(\cong\)400 nm. Decay kinetics of this luminescence is characterized by a time constant of \(\tau\cong\)405 ns, which is close to the typical values for 5d→4f transitions of Eu\(^{2+}\) ions in inorganic compounds.

Keywords: nanoparticles, Al\(_2\)O\(_3\), luminescence properties, Eu, defects
