Abstract
Powder samples of KSrPO4 doped with Eu2+ and Ce3+ were prepared by combustion-assisted synthesis. Their structures and photoluminescence spectra were systemically studied. Energy transfer from Ce3+ to Eu2+ was observed by investigating the optical properties from photoluminescence spectra in Eu2+ single doped and Ce3+–Eu2+ co-doped KSrPO4. The enhancement of UV excitation is attributed to energy transfer from Ce3+ to Eu2+, and Ce3+ plays a role as a sensitizer. Ce3+–Eu2+ co-doped KrSrPO4 powders can possibly be applied as blue phosphors in the fields of lighting and display.
