Abstract
Yb 3+ spectroscopic properties are given in garnet crystals. Especially, radiative energy transfer between Yb 3+ ions and non-radiative energy transfer between Yb 3+ and unexpected rare earth impurities are occurring as quenching mechanisms. Other mechanisms are also suspected from Yb 3+ pairs, OH- groups and even traces of Yb 2+.
