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. © 2009 The Electrochemical Society.
