摘要	BaMg2Al6Si9O30:Eu2+ phosphors are synthesized by the solid-state reaction method and their photoluminescence (PL) properties are investigated. The ultraviolet emission originates from Eu2+(I) substituting for Ba2+ sites, whereas the blue emission is attributed to Eu2+(II) substituting for Mg2+ sites. With increasing Eu2+ doping concentrations, the blue emission band shifts to long wavelength and the PL intensity ratio of blue to ultraviolet emission increases. Energy transfer between the two different Eu2+ ions is analyzed by photoluminescence excitation and emission spectra, and lifetimes. Results indicate that the emission spectra can be tuned by changing Eu2+ contents. We have also demonstrated that BaMg2Al6Si9O30:Eu2+ phosphor is a kind of potential phosphor for fluorescent lamps.
