| Abstract: | Eu3+-doped triple phosphate Ca8MgR(PO4)7 (R=La, Gd, Y) was synthesized by the general high-temperature solid-state reaction. Excitation and emission spectra as well as luminescence decay were used to characterize the phosphors. Photoluminescence excitation and emission spectra showed that the phosphor could be efficiently excited by UV-vis light from 260 to 450 nm to give bright red emission assigned to the transition (5D0→7F2) at 612 nm. The richness of the red color has been verified by determining their color coordinates (X, Y) from the CIE standard. |
