| 中文摘要 | Uniform SiO2@CaMoO4:Eu3+ red phosphor has been synthesized by sol-gel method, and its luminescence properties have been studied by fluorescence spectrometer. The structure and morphology of the SiO2@CaMoO4:Eu3+ red phosphor have been investigated by transmission electron microscopy (TEM), scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS), X-ray diffraction (XRD), and FT-IR spectrometer. Results indicate that phosphor particles have a core-shell structure and the thickness of the SiO2-shell is about 60 nm. In addition, the luminescent intensity of SiO2@CaMoO4:Eu3+ red phosphor has been greatly enhanced with respect to CaMoO4:Eu3+ phosphor. But the lifetime tau value of SiO2-coated CaMoO4:Eu3+ is slightly smaller than that of non-coated CaMoO4:Eu3+. (C) 2012 Elsevier Inc. All rights reserved. |
