A series of Ba2Mg(PO4)2:Ce3+, Eu2+ phosphors were synthesized by the traditional high temperature solid-state method, and the crystal structures and luminescence properties of the samples were discussed systematically. The energy transfer from Ce3+ to Eu2+ in Ba2Mg(PO4)2 was proved to be of resonant type via a dipole–dipole interaction mechanism. With a precisely controlled relative proportion of Ce3+/Eu2+, the emission color of the samples can vary from blue (0.157, 0.071) to white (0.352, 0.332) and ultimately to yellow (0.452, 0.466) under the 323 nm ultraviolet light radiation excitation. The result reveals that the Ba2Mg(PO4)2:Ce3+, Eu2+ phosphor may have potential application as a single-phased white-emitting phosphor for light emitting diodes.
