“…E.g., the 1540 nm emission of Er 3þ is an ideal optical communication wavelength. Hence, Ln-doped components are very promising materials for the fabrication of waveguides, [25] fiber lasers, [26,27] luminescent liquid crystals, [28] or light-emitting diodes (LEDs). [29,30] Additionally, the visible www.afm-journal.de lanthanide emission is already used in fluorescent lamps.…”

With the technique of synchrotron X‐ray activation, molecule‐like, non‐plasmonic gold and silver particles in soda‐lime silicate glasses can be generated. The luminescence energy transfer between these species and lanthanide(III) ions is studied. As a result, a significant lanthanide luminescence enhancement by a factor of up to 250 under non‐resonant UV excitation is observed. The absence of a distinct gold and silver plasmon resonance absorption, respectively, the missing nanoparticle signals in previous SAXS and TEM experiments, the unaltered luminescence lifetime of the lanthanide ions compared to the non‐enhanced case, and an excitation maximum at 300–350 nm (equivalent to the absorption range of small noble metal particles) indicate unambiguously that the observed enhancement is due to a classical energy transfer between small noble metal particles and lanthanide ions, and not to a plasmonic field enhancement effect. It is proposed that very small, molecule‐like noble metal particles (such as dimers, trimers, and tetramers) first absorb the excitation light, undergo a singlet‐triplet intersystem crossing, and finally transfer the energy to an excited multiplet state of adjacent lanthanide(III) ions. X‐ray lithographic microstructuring and excitation with a commercial UV LED show the potential of the activated glass samples as bright light‐emitting devices with tunable emission colors.

“…Among the first methods used to create nanostructured silver clusters within glasses are ion implantation [105][106][107] and sol-gel techniques [7,[108][109][110][111]. Ion implantation does not allow an effective control on the size distribution of nanoclusters within the matrix, and is therefore currently explored mainly for the formation of exotic nanostructures such as core-shell or alloy particles.…”

“…The use of metal sensitizers for increasing the pumping efficiency of rare earths will be briefly reminded in this section, with particular focus on the specific field of Er-doped Ag exchanged sol-gel glasses [15][16][17][18]. The combination of sol-gel and ion-exchange techniques is a very efficient way to realize optical waveguides with controlled properties (extended reviews on Ag ion-exchange can be found in refs.…”

“…A different approach is related to the use of semiconductor or metal sensitizers, which presents typically a broad absorption spectrum and an efficient energy transfer to the rare earth. This field was strongly investigated in the last decades for optical amplification in Er 3 + doped waveguides [15][16][17][18], but also the application of Ag nanostructures and Yb 3 + ions for PV cells received attentions in a very recent paper by Ma et al [19].…”

The efficiency of solar cells may be improved by better exploitation of the solar radiation managing the photons coming from the solar spectrum to better fit the absorption band of the employed solar cells. This can be done by inserting in the front or rear of the solar cell an optically active layer doped with rare earth ions which acts as down-converter or up-converter. This is just one of the possibilities that involve several structures and geometries such as waveguide configuration and radiation trapping systems. Moreover, the use of antenna systems or other sensitizers can improve significantly the optical performance of the down converting layer. In this work we will give a short review regarding the research already developed by the team in the field of down-conversion process and rare earth sensitizing.On the one hand we will focus the attention on the cooperative energy transfer between donor and acceptor ions taking as example the interaction among one Tb 3+ ion and two Yb 3+ ions in a 70Si02-30Hf02 glass-ceramic waveguide and the Pr 3+ to Yb 3+ energy transfer in bulk fluoride glasses. On the other hand we will show how silver nanoparticles can enhance the absorption efficiency of rare earths.
