N2 - Series of silica-based glasses doped with La2O3, Eu2O3, and Sm2O3 was synthesized to host luminescent silver clusters formed via Na+-Ag+ ion exchange and heat treatment. Photoluminescence spectra of the glasses with Eu3+ or Sm3+ ions consist of broad white emission from silver clusters and characteristic bands of rare-earth ions. Energy transfer between silver clusters and Eu3+ or Sm3+ ions was studied by controlling luminescence quantum yield and lifetime of silver clusters. Rare-earth doping of the studied glass decreases the amount of forming silver clusters, therefore, the quenching efficiency of Eu3+ and Sm3+ ions was calculated in comparison to the glasses doped by La3+. It was shown that quantum yield of cluster luminescence decreases faster than the fluorescence and phosphorescence lifetime in the presence of Eu3+ or Sm3+ ions. Difference in quenching efficiency of luminescence quantum yield and emission lifetime of silver clusters was explained by the coexisting of two different mechanisms of quenching.
