| 中文摘要 | (y, gd) bo3:eu3+ particles coated with nano-hematite were prepared by a facile method i for example (humid) solid phase reaction at room temperature. the resulted hematite-coated (y, gd)bo3:eu3+ particles were characterized by scanning electron microscopy (sem), energy dispersive spectrometer (eds) analysis, x-ray diffraction (xrd), x-ray photoelectron spectra (xps), and photoluminescence spectra (pl). the sem and eds analyses indicate that the particles are coated with a very thin layer of iron oxide. xps results further confirmed that the coating was hematite, and the coating thickness was in nanometer range. xrd patterns showed that either the hematite coating was too thin or the content of hematite was too small, so that the xrd cannot detect it. the emission spectra illustrate that the peak near 580 nm disappears due to the coating of iron oxide, and when the coating is very thin, the ratio of d-5(0)-> f-7(2) to d-5(2)-> f-7(1) of coated particles is higher than that of uncoated ones, which indicates that the color purity of the phosphor is increased by coating nano-hematite. |
