Pyrophosphates K 2 AEP 2 O 7 (AE = Ca, Sr) prepared by the classical solid‐state technique and activated with Ce 3+ are described. Intense emission was observed in K 2 AEP 2 O 7 (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 K 2 SrP 2 O 7 :Ce 3+ and at 539 nm in K 2 CaP 2 O 7 :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+ . Copyright © 2015 John Wiley & Sons, Ltd.
