Abstract:

The phosphors, Ba5-3x/2B4O11xEu3+(x=0.02~0.22), were synthesized by high-temperature solid-state reaction method. The luminescence property of Ba5-3x/2B4O11xEu3+ was studied in this paper. The phase and surface topographies of as-prepared samples were characterized by X-ray diffraction(XRD) and scanning electron microscope(SEM). This phosphor can be effectively excited at 393 nm and the emission peaks are located at 596 nm, 621 nm, 657 nm and 706 nm corresponding to the 5D0-7FJ(J=1,2,3,4) transition of Eu3+ ions, respectively. Therein the 5D0-7F2 electric dipole transition of Eu3+ ions, which locates at 621 nm, is the strongest wave crest. Investigation of Eu3+ content-dependent emission spectra indicates that x=0.16 is the optimum doping content of Eu3+ ions in the Ba5B4O11 host.
