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 0.25～0.3 μm.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 nm light and exhibit the characteristic red emission of Eu3+ 5D0→7F2transition.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.; 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 0.25～0.3 μm.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 nm light and exhibit the characteristic red emission of Eu3+ 5D0→7F2transition.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.; 国家自然科学基金(No.50472020); 河北省自然科学基金(No.08B012); 河北师大博士基金(No.L2006B15)资助项目
