英文摘要	A series of single phase Ba9-x-ySc2-zSi6O24:xCe,yEu,zMn phosphors was synthesized by high-temperature solid-state reactions. The luminescent properties of single-doped, co-doped and tri-doped Ce3+/Eu2+/Mn2+ in the host Ba9Sc2Si6O24 were studied on the basis of the photoluminescence excitation/emission spectra, photoluminescence decay behaviors and time resolved emission spectra. Two types of luminescent centers of Eu(1)/Eu(2,3) as well as Ce(1)/Ce(2,3) occupying different crystallography sites were confirmed, and the sensitizing effects of Ce3+ -> Eu2+, Ce2+ -> Mn2+ and Eu2+ -> Mn2+ were clearly observed. In the tri-doped samples, Eu2+ competed with Mn2+ for the energy transferred from Ce3+ and also transferred its observed energy to Mn2+. Furthermore, the tri-doped Ba9Sc2Si6O24 phosphors emitting white light with various correlated color temperatures were obtained by adjusting the relative content of Ce3+, Eu2+ and Mn2+.; National Natural Science Foundation of China [21371015]; SCI(E); EI; ARTICLE; xpjing@pku.edu.cn; 85; 69458-69465; 5
