Fluorescence enhancement induced by the presence of small silver particles in Eu3+ doped materials

Interpretation of europium(III) spectra

“…One way of shortening  rad is by placing the europium(III) complex in the vicinity of metallic surfaces or in contact with metallic nanoparticles [764][765][766][767]. Most often silver is used.…”

Localized Surface Plasmon Resonances: Noble Metal Nanoparticle Interaction with Rare-Earth Ions

“…Using the results obtained by O.L. Malta et al [66], the effective electric field can be written as: …”

“…Fluorescence spectra of the Eu 3+ ions in the presence (a) and in the absence (b) of Ag NPs.The silver concentration is 7.5 in weight percent. The matrix glass composition can be found in [66]. (b).…”

Frequency upconversion in a Pr3+ doped chalcogenide glass containing silver nanoparticles

“…15 For instance, enhancement of Eu 3+ luminescence was reported in a fluoroborate glass containing silver NPs a long time ago. 16 Later, experiments were presented where local field or energy transfer effects change the luminescence of REI in fluoroborate and silicate glasses. 17,18 Presently, this approach to increase the luminescence in REI doped glass is receiving renewed attention due to the large interest in nanophotonics.…”
