Abstract

The silica sol-gel derived glasses co-doped with Cu_xO and Cu_xSe nanoparticles and Eu³⁺ ions have been fabricated. The analysis of luminescence spectra of a series of glasses with different composition allows us to suppose the direct energy transfer between copper oxide nanoparticle and Eu³⁺ ion. A luminescence signal of europium ions occurs as the result of excitation of the complex active centres (SiO₂:Cu₂O:Eu³⁺) in the absorption range of copper oxide.
