ResumoThe near UV, visible and near IR emissions in YAG:Tm3+ are investigated after selective one photon pumping of the 1I6, 1D2 or 1G4 manifold. Reduction of the fluorescence lifetimes as well as non-exponentiality of the decays at short times, which appear with increasing activator concentration, are indications of the cross-relaxation quenching of these excited state emissions.
