Abstract
The compound Sr 2Mg 3P 4O 15 singly and doubly doped with Eu 2+ and Mn 2+ was investigated. Phosphor Sr 2Mg 3P 4O 15:Eu 2+, Mn 2+ shows a broad blue emission band and a red emission band, which originates from the Eu 2+ occupying the Sr 2+ sites and the Mn 2+ occupying the Mg 2+ sites, respectively. The resonant type energy transfer from Eu 2+ to Mn 2+ was demonstrated, and the energy transfer efficiency was also calculated according to their PL spectra. Based on the principle of energy transfer, the PL intensity ratio of Eu 2+ and Mn 2+ could be appropriately tuned by adjusting the contents of activators. We also illuminated that the phosphor Sr 2Mg 3P 4O 15:Eu 2+, Mn 2+ could be used as a potential candidate for blue and red double color emitting phosphor in near-UV white light-emitting diodes (LEDs).
