Mn2+/Eu2+ co-activated Sr3Si6O3N8 phosphor was synthesized by conventional solid state reaction. Sr3Si6O3N8: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 Sr3Si6O3N8:Eu2+ could be efficiently enhanced by co-doping with Mn2+ ions. The energy transfer mechanism between Eu2+ and Mn2+ in Sr3Si6O3N8:Eu2+, Mn2+ phosphors is dominated by electric multipole effect interaction.
