Abstract Novel red phosphor, Eu3+-doped oxyphosphate (La3PO7∶Eu3+), was synthesized by a solid state method under high temperature. All the starting materials were analytical grade. La2O3, Eu2O3 and (NH4)2HPO4 weighed in appropriated molar ratios and ground in an agate mortar. Then the powder was treated under 1 000 ℃. The crystal phase of La3PO7∶Eu3+ was investigated by X-ray diffraction (XRD) using a Cu target radiation resource (λ=1.540 78 ?) and exhibited prominent peaks accordant with JCPDS standard card (33-0720) of La3PO7 in monoclinic phase. Emission and excitation spectra of La3PO7∶Eu3+ were recorded at room temperature using a fluorescence spectrometer (Hitachi F-4500). Under 254 nm excitation, intense red fluorescence was observed from La3PO7∶Eu3+, which was assigned to the 5D0→7F2 transition of Eu3+ ions. The intensity of the 5D0→7F2 transition is stronger than that of the 5D0→7F1 transition, showing that the Eu3+ ions were in the non-centrosymmetric sites in La3PO7. The CommissionIn-ternational DeL″ Eclairage (CIE) coordinate of La3PO7∶Eu3+ is (0.63,0.37) in the red area of CIE1931 XY chromaticity coordinate graph and close to that of Y2O3∶Eu3+, but the cost of La3PO7 host is lower. This novel material may have potential applications in plasma display panels and Hg-free fluorescent lamps in the future.
