Cooperative luminescence as a defining process for RE-ions clustering in glasses and crystals
TLDR
In this article, cooperative luminescence is used as a defining process for ions cluster which can help to distinguish them from energy transfer processes and so to separate processes occurring at different distances.About:

Upconversion and Anti-Stokes Processes with f and d Ions in Solids
TL;DR: Before the 1960s, all anti-Stokes emissions, which were known to exist, involved emission energies in excess of excitation energies by only a few kT and were linked to thermal population of energy states above excitation states by such an energy amount.

Radiation trapping and self-quenching analysis in Yb3+, Er3+, and Ho3+ doped Y2O3
TL;DR: In this paper, the combined case of self-trapping and self-quenching in the lifetime analysis of Yb, Er, and Ho doped Y 2 O 3 single crystal fiber is studied.

Towards rare-earth clustering control in doped glasses
F. Auzel,Philippe Goldner +1 more
TL;DR: In this paper, a new doping principle is proposed based on the recognition that introducing the doping RE into the glass composition through given precursor crystals with large RE-RE distances, allows some control of the clustering of rare-earth ions and of their self-quenching.

Blue cooperative upconversion in Yb3+-doped multicomponent sol-gel-processed silica glass for three-dimensional display
TL;DR: In this paper, the authors proposed using blue cooperative upconversion of ytterbium (Yb3+) ions produced by a one-color one-beam pumping scheme for a three-dimensional fluorescence display.

Materials and devices using double-pumped-phosphors with energy transfer
TL;DR: In this paper, the basic phenomena involved in double-pumped phosphors with energy transfer are described and discussed and the role played by successive multiple transfers as well as cooperative processes giving rise to antistokes fluorescence is emphasized for the different kinds of doping which have been used.

Upconversion processes in coupled ion systems
TL;DR: In this article, the basic processes involved in up-conversion by energy transfer (Addition de Photons par Transferts d'Energie: APTE effect) are recalled.

Concentration-dependent upconversion in Er/sup 3+/-doped fiber amplifiers: Experiments and modeling
TL;DR: In this article, eight different fibers were studied to examine upconversion as a function of erbium concentration below 1000 ppm by weight, and a computer model of two-particle up-conversion made it possible to estimate the up conversion coefficient used in a rate-equation model.

Optical spectroscopy of the dimer system Cs3Yb2Br9
Markus P. Hehlen,Hans U. Güdel +1 more
TL;DR: In this paper, the crystal field splitting of Yb3+ in Cs3Yb2Br9 was determined and can be rationalized in terms of a trigonally distorted YbBr63− octahedron.
