The article presents the possible mechanisms of interaction between emission of Eu 3+ ions and surface plasmon resonance (SPR) from Ag 0 nanoparticles. The antimony-germanate glasses were synthetized by standard melt-quenching method. The influence of high-phonon glass forming compounds on excitation and luminescence spectra was analysed. Also, we showed that Sb 2 O 3 is a mild reducing agent of noble metal ions. This mild reduction property enables thermochemical reduction of Ag + to Ag 0 in a single-step during the melting process. The energy transfer mechanisms between Eu 3+ ions and Ag 0 nanoparticles were also discussed in terms of local field effect of Ag 0 nanoparticles. Full Text: PDF References S. Chatterjee, S. K.
