Abstract

Enhancement of the T 1g 4 (G4) → A 1g 6 (S6) red emission of MgGe O3:1% Mn₂+ with addition of Yb2O₃is reported. The initial phosphorescence in the Yb₂O₃codoped sample is an order of magnitude stronger than that of the Yb₂O₃-free sample. Thermoluminescence spectra indicate that the introduction of Yb³⁺ into the host produces traps with a suitable depth, resulting in the enhanced red phosphorescence of Mn²⁺. The possible mechanism for this phenomenon is explained by a competitive trapping model.
