Stimulated Luminescence of Europium Ions in Highly Scattering Lu2O3:Eu Nanomaterials

  • Published:
Bulletin of the Russian Academy of Sciences: Physics Aims and scope

Abstract

Strong pulsed nonresonant photoexcitation is used to study the spectral and kinetic characteristics of the stimulated luminescence of red intracenter electronic transitions of the Eu3+ ion (580–650 nm) in densely packed nanopowders and nanospheres (diameter, 100–270 nm) of the composition Lu2O3:Eu (5–10 at %). The observed glow spot (~1 mm) is much larger than a laser spot focused on a powder sample (~100 μm). The recorded glow pulse slows upon an increase in the detected area, testifying to the inhomogeneity of luminescent radiation and its diffusion from the region of the photoexcitation spot.
