Abstract

Increases of emission intensities for Eu³⁺ at the S₆ site relative to that at the C₂ site have been observed as UV excitation wavelength decreases from 300 to 200 nm in both bulk and nanocrystalline cubic Y₂O₃:Eu³⁺. Analysis of excitation spectra suggests that the energy transfer from the host prefers to the S₆ site. In addition, spectral red-shift has been found in both charge transfer bands in nanocrystalline Y₂O₃:Eu ³⁺ compared to the bulk material. The number ratio of S₆ sites to C₂ sites is also smaller in nanocrystalline Y ₂O₃:Eu³⁺ than that in the bulk one.
