摘要：
Mn2+/Eu2+ co-activated 5r"Si603N18 phosphor was synthesized by conventional solid state reaction. 5r3Si603N8:Eu2', Mn2' green-emitting phosphor could be effectively excited by UV-visible light from 300 nm to 500 nm, which matched well with the emission of UV and blue LED chips. The luminescence intensity of Sr3Si603N18:Eu2' could be efficiently enhanced by co-doping with Mn2+ ions. The energy transfer mechanism between Eu2+ and Mn2- in Sr3Si603N18:Eu2', Mn2+ phosphors is dominated by electric multipole effect interaction. 2014 Published by Elsevier B.V.
