Energy transfer between silver clusters and europium Eu3+ ions in photo-thermo-refractive glasses

Three-Dimensional High Spatial Localization of Efficient Resonant Energy Transfer from Laser-Assisted Precipitated Silver Clusters to Trivalent Europium Ions

“…The co-doping of glasses with both rare earth ions and noble metal ions has been increasingly reported [15][16][17][18] for optoelectronic devices such as white light emitting diodes, three-dimensional displays, and solar cells [15,[17][18][19][20]. Indeed, efficient energy transfer between silver species and europium ions was described and achieved in various materials such as glasses and zeolite materials [15,16,[21][22][23][24][25][26]. In glasses, in addition to the traditional melt technique to incorporate silver species with rare ions, different methods of preparation have been described, such as the ion-exchange processes.…”

“…The modification of the quantum yield of fluorescence emission has been described thanks to the presence of silver clusters and silver nanoparticles [15]. An enhancement of the rare earth emission by energy transfer from silver clusters to Eu 3+ ions has been observed in various matrices, such as in silicate [22,23] or borate [27].…”

Tunable Visible Light and Energy Transfer Mechanism in Tm3+ and Silver Nanoclusters within Co-Doped GeO2-PbO Glasses

“…Consequently, the scientific literature has witnessed a surge in exploration involving diverse glass compositions as potential hosts for Ag NCs. These compositions span zinc borate CABAl [13], fluorophosphate [14][15][16][17][18][19], borates [20], and borosilicates [21,22], among other glass matrices [23][24][25][26][27], thereby broadening the possibilities of Ag NC-based photonic applications. The applications of this technology span a wide array of photonic advancements, including photovoltaic devices, flexible screens, sources for white light [28], fiber [29,30], including wavelength tuning [31,32].…”

“…In the case of Ag NPs, this enhancement is due to the generation of an amplified local electromagnetic field in the neighborhood of the RE ions [35,36]. Conversely, in the case of Ag NCs, mechanisms involving direct energy transfer (ET) [9][10][11][12][13][18][19][20][21][22]27] and Förster resonance ET [15] have been reported as the means of achieving this enhancement. In certain instances, the overlap of the PL bands related to Ag NCs and the ones corresponding to RE ions can result in the production of white light and also the tuning of the visible emission as a function of the excitation wavelength.…”
