文摘

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.
