| 英文摘要 | a series of color-tunable sr2ceo4:eu3+ phosphors have been successfully synthesized. the rietveld refinement was firstly used to probe the phase purity and the structure of sr2ceo4:eu3+. the photoluminescence excitation spectra exhibit that the phosphors show a broad excitation band from 200 to 400 nm, which concurs well with the commercial near-uv led. the photoluminescence spectra vary with the dopant content due to the energy transfer and the tunable blue-red color tan be simply achieved by altering the doped eu3+ ions concentrations. on the basis of the inokuti-hirayama theory, we obtained that the dipole-dipole interaction type takes charge for the energy transfer from the ce4+-o2- charge-transfer state transition to eu3+ ions and the schematic was plotted to illuminate the possible energy transfer process. the experimental results indicate that sr2ceo4:eu3+ phosphors may be potentially used as promising single-phased phosphors for near-uv white light-emitting diodes applications.
