Abstract
CaMoO4:Eu3+@TiO2 red phosphors were synthesized via a sol-gel method. The morphology and structure of the CaMoO4:Eu3+@TiO2 red phosphor have been investigated by transmission electron microscopy (TEM), energy dispersive spectroscopy(EDS), X-ray diffraction(XRD), and Fourier- transform infrared spectroscopy (FT-IR). The result indicated that TiO2 layer with 25 nm was uniformly coated over the phosphors surface. Meanwhile, CaMoO4:Eu3+@TiO2 red phosphors showed obviously thermal stability compared to CaMoO4:Eu3+ phosphors, indicating it is an effective way to improve the useful lifetime of CaMoO4:Eu3+ red phosphors..
