摘要：
To synthesize green-emitting SrSi2O2N2 phosphor, boron-coated Eu2O3 was used as an activator with different crucibles. This phosphor showed higher emission intensity than phosphor obtained using boron nitride and an alumina crucible. The synthesized green-emitting phosphors obtained using a carbon crucible were crystallized much better and showed higher emission intensity. The emission spectra typically showed a single broad green emission band corresponding to the 5d -> 4f transition of Eu2+ ions under excitation of 450 nm. This green-emitting phosphor is expected to be applied to next-generation white LEDs.
