Abstract
In this study, Eu3+ doped Ca(WO4)1−x(MoO4)x phosphors were synthesized via high temperature solid-state reaction. Compared with the Eu3+ activated CaWO4 sample, an increment of MoO3 doping concentration could improve the emission intensity. Improved red afterglow originating from the 5D0 to 7FJ (J=0, 1, 2, 3, 4) transitions of Eu3+ was observed after appropriate amount of MoO3 was added, and the optimal MoO3 doping concentration was experimentally determined to be 0.02. The proposed explanation for the afterglow property was also discussed.
