Retentiveness of rare earth elements in garnet with …
Incorporation of rare earth elements (REE) in garnet enables garnet chronology (Sm-Nd, Lu-Hf), and imparts a garnet-stable signature on cogenetic phases, which allows petrochronology and general petrogenetic tracing of garnet stability in minerals and melts. Constraints on the uptake and redistribution mechanisms, as well as …

(PDF) Rare‐earth garnet selective emitter
The garnet structure and its many subgroups have been successfully used as hosts for rare earth ions, introduced as substitutional impurities, in the development of solid state laser crystals 7. Doping, dependent on the particular ion and crystal structure, may be as high as 100 at. % (complete substitution of yttrium ion with the rare earth ion).

Quantifying antisite defect concentrations in yttrium aluminum garnet
The dominant point defect in many rare-earth (RE) doped garnets is thought to be antisite occupation of Y 3+ or the rare earth dopant on the Al 3+ site in the host crystal structure [8, 9, 12, 13]. These antisite defects are believed to be the cause of the large inhomogeneous broadening observed for the optical transitions of RE-doped …
