M 5 (PO 4 ) 3 F:Eu 2+ (M = Ca and Ba) co‐doped with Ce 3+ phosphors were successfully prepared by the combustion synthesis method. The introduction of co‐dopant (Ce 3+ ) into the host enhanced the luminescent intensity of the M 5 (PO 4 ) 3 F:Eu 2+ (M = Ca and Ba) efficiently. Previously, we have reported the synthesis and photoluminescence properties of same phosphors. The aim of this article is to report energy transfer mechanism between Ce 3+ ➔Eu 2+ ions in M 5 (PO 4 ) 3 F:Eu 2+ (M = Ca and Ba) phosphors, where Ce 3+ ions act as sensitizers and Eu 2+ ions act as activators. The M 5 (PO 4 ) 3 F:Eu 2+ (M = Ca and Ba) co‐doped with Ce 3+ phosphor exhibits great potential for use in white ultraviolet (UV) light‐emitting diode applications to serve as a single‐phased phosphor that can be pumped with near‐UV or UV light‐emitting diodes.
