Abstract
Well-dispersed Eu3+ and Sr2+ co-doped YVO4 luminescent particles (YVO4:Eu3+,Sr2+) on the submicron scale were prepared by a facile solvothermal method at low temperature. The effect of Sr2+ doping on the luminescence of YVO4:Eu3+,Sr2+ particles was investigated by fixing the Eu3+ doping concentration at 7 mol%. It was found that the luminescence intensity of the as-prepared YVO4:Eu3+,Sr2+ particles increased with the Sr2+ doping concentration x to reach a two-fold enhancement when x = 5 %, and then decreased for higher x. We also investigated the effect of thermal annealing on the luminescence properties of the YVO4:Eu3+ and YVO4:Eu3+,Sr2+ particles. A remarkable enhancement in their luminescence properties was observed after annealing at 900 °C in air for 30 min. It was showed that the annealed YVO4:Eu3+,Sr2+ particles exhibited a two-fold stronger emission than the annealed YVO4:Eu3+. This work indicates that Sr2+ doping is beneficial to the luminescence enhancement for both the as-prepared and annealed YVO4:Eu3+,Sr2+ particles.
