Europium-doped aluminophosphate glasses prepared by the melt-quenching technique have been studied by photoluminescence (PL) and X-ray photoelectron spectroscopy (XPS). The effects of silver and tin doping, and of further thermal processing on Eu 3+ ions luminescence have been assessed. For the glass system containing only europium, Eu 3+ PL observed under UV excitation is suggested...
Glasses containing silver, tin and europium were prepared by the melt-quenching technique with silver nanoparticles (NPs) being embedded upon heat treatment (HT). An intensification of Eu 3+ ions emission was observed for non-resonant excitation around 270nm, corresponding to UV absorption in the material. Optical measurements suggest that light absorption occurs at single Ag + ions...
