The luminescent properties of Sr3V2−xPxO8 (0 ⩽ x ⩽ 2), Eu3+ doped Sr2.7Eu0.2V2−yPyO8 (0 ⩽ y ⩽ 2) and Sr3−3zEu2zV0.8P1.2O8 (0 < z ⩽ 0.3) have been investigated. For the Sr3V2−xPxO8 (0 ⩽ x ⩽ 2) samples, the VO43- activation and emission intensity reaches the strongest as x = 1.6. For the Sr2.7Eu0.2V2−yPyO8 (0 ⩽ y ⩽ 2) samples, an appropriate amount of phosphorus doping enhances the Eu3+ emission with the strongest emission occurring at y = 1.2. For the Sr3−3zEu2zV0.8P1.2O8 (0 < z ⩽ 0.3) sample with the phosphorus content fixed at 1.2, it exhibits the most intense emission as Eu3+ concentration reaches at z = 0.2. Our results indicate that the introduction of the PO43- plays an important role in the photoluminescence properties of the studied samples and the relevant mechanism has been discussed.
