Using the combustion method, red emitting Sr4Al14O25:Eu 3+ and Sr4Al14O25:Sm 3+ phosphors were synthesized. The properties of photoluminescence were also studied. The red (614 nm) emission from Sr4Al14O25:Eu 3+ phosphor, at excitation 394 nm. The excitation peak was around 404 nm and was attributed to 6 H5/2→ 4 F7/2, while the emission spectrum had emission peaks at 565 nm and 603 nm for Sr4Al14O25:Sm 3+ phosphor. Furthermore, the chromaticity coordinates of Sr4Al14O25:Eu 3+ and Sr4Al14O25:Sm 3+ phosphors were found in the red region (0.677, 0.322) and (0.640, 0.359) by the Commission International de l'Eclairage respectively. According to the current findings, Sr4Al14O25:Eu 3+ and Sr4Al14O25:Sm 3+ phosphors can be used as a red emitting phosphor in near-ultraviolet (n-UV) based w-LEDs.
