| 中文摘要 | The hyperfine red phosphors, NaEu(MoO4)(2), were synthesized by hydrothermal and subsequent heat-treatment processes. The NaEu(MoO4)(2) phosphors show regular elliptical morphologies, and the particle sizes of 0.25 similar to 0.3 mu m. The excitation spectra located at short-wavelength UV region belong to the interweave broad charge transfer bands of Mo6+-O2- and Eu3+-O2-, and the three sharp lines around 395 nm, 465 nm and 535 nm are ascribed to the Eu3+ 4f excitation transitions. All of the samples can be excited with near-UV 395 run light and exhibit the characteristic red emission of Eu3+ D-5(0)-> F-7(2) transition. The relative red emission intensities of the optimum phosphors reach two-fold as compared with that of the commercial phosphors. The submicro-phosphors may be applied as red phosphors for white light emitting diodes. |
