摘 要：Ca2RE8（SiO4）6O2:A （RE=Y, Gd; A=Pb2+, Mn2+） phosphor films were dip-coated on quartz glass substrates through the sol-gel process. X-ray diffraction （XRD）, photoluminescence （PL） spectra as well as lifetimes were used to characterize the resulting films. Under short wavelength UV excitation, the film showed a red emission with medium intensity. The decay curve of Mn2+ luminescence in Ca2Gd8（SiO4）6O2:Pb Mn film could be fitted into a single exponential function. The lifetime of Mn2+ was 10.21 ms in Ca2Gd8（SiO4）6O2.
