Abstract
A series of Ce3+ doped and Ce3+-Eu2+ co-doped Ba2MgSi2O7 phosphors was prepared via a high-temperature solid-state reaction technique. The photoluminescence properties, which include synchrotron radiation VUV-UV excitation spectra, emission spectra and concentration effect, thermal stability of Ce3+ are investigated. Hence the energies of the crystal field split 5d excited states of Ce3+ are determined. Due to spectral overlap, the energy transfer from sensitizer Ce3+ to activator Eu2+ in Ba2MgSi2O7:Ce3+, Eu2+ occurs, and the mechanism is demonstrated to be an electric dipoleâdipole interaction.
