Structure and Anti-Stokes Luminescence of Yb-containing Glass Co-doped with Eu, Ho and Er

The aim of our work was synthesis of transparent silicious media high-doped with Yb–Er, Yb–Ho and Yb–Eu and determination of the media structure and spectral-luminescent properties in the anti-Stokes region at excitation through the Yb3+ ions

Optical Materials Activated with CeO2:Ln3+ Nanoparticles

Silica glasses and siliceous powders activated with CeO2:Ln3+ (Ln ¹ Ce) nanoparticles were synthesized by the sol-gel method and their structural and spectral-luminescent properties were investigated. It is shown that the main features of the Ln3+ ions are a high relative intensity of magnetic dipole transitions and sufficiently effective sensitization of their luminescence with labile photoreduced (Ce4+)- ions by means of superexchange mechanism or/and by transfer of electron
