title: Luminescence and energy transfer in Ce3+, Mn2+- doped K2AEP2O7 (AE = Ca, Sr) phosphor.
abstract: Pyrophosphates K2AEP2O7 (AE = Ca, Sr) prepared by the classical solid-state technique and activated with Ce(3+) are described. Intense emission was observed in K2AEP2O7 (AE = Ca, Sr). The effect of Mn(2+) co-doping was studied. The broad emission peak of Mn(2+) was observed at 534 nm in K2 rP2O7:Ce(3+) and at 539 nm in K2CaP2O7:Ce(3+), Mn(2+). Mn(2+) emission was greatly enhanced by addition of the sensitizer Ce(3+) due to efficient energy transfer from Ce(3+) to Mn(2+).
