摘要Enhanced luminescent SiO2@LaPO4:Ce3+/Tb3+phosphors were prepared using a homogeneous precipitation method followed by a subsequent heat-treatment process. The products were characterized by XRD, SEM, TEM, HRTEM, XPS, and photoluminescence (PL). The XRD results demonstrated that all of the diffraction peaks can be well indexed to the pure monoclinic phase. The SEM and TEM images indicated that the phosphors have perfect spherical shapes with a narrow size distribution and no agglomeration. The EDS and XPS analysis revealed that LaPO4:Ce3+/Tb3+layers have been deposited successfully on SiO2particles. The PL results demonstrated the samples annealed at 800 °C have the strongest green emission. © 2017 Optical Society of America under the terms of the OSA Open Access Publishing Agreement.
