| 英文摘要 | A series of Ca10Na(PO4)(7):Ce3+/Tb3+/Mn2+ (CNPO:Ce3+/Tb3+/Mn2+) phosphors with high brightness were synthesized by high-temperature solid-state method. X-ray diffraction (XRD), scanning electron microscopy (SEM), diffuse reflectance spectra (DRS), photoluminescence (PL) spectra, luminescence decay curves and thermally stability were performed to characterize the as-prepared samples. For Ce3+-doped samples, an intense and broad band emission is present under 265 nm excitation. When Ce3+ and Tb3+ are codoped, energy transfer (ET) process from Ce3+ to Tb3+ is demonstrated with electric dipole-dipole interaction. The internal and external quantum efficiencies (QEs) of CNPO:0.15Ce(3+), 0.04Tb(3+), 0.005Mn(2+) are measured to 76.79% and 54.11% under 265 nm excitation and temperature-dependent PL intensity can remain 51.78% at 150 degrees C of its initial intensity at 25 degrees C. It is indicated that single-phased white light-emitting CNPO:Ce3+/Tb3+/Mn2+ phosphor can serve as a promising phosphor for illumination devices. (C) 2018 Published by Elsevier B.V. |
