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 Eu3+ ions emission was observed for non-resonant excitation around 270 nm, corresponding to UV absorption in the material. Optical measurements suggest that light absorption occurs at single Ag+ ions and/or twofold-coordinated Sn centers followed by energy transfer to europium which results in populating the 5D0 emitting state in Eu3+. After HT at 843 K, a quenching effect is observed on Eu3+ luminescence with increasing holding time in the 350-550 nm excitation range. The quenching effect shows with the presence of Ag NPs which may provide multipole radiationless pathways for excitation energy loss in europium ions.
