摘要
The present invention provides a green light-emitting phosphor for a light-emitting device excited by vacuum ultraviolet rays, a light-emitting device, and a method of preparing the same. The green light-emitting phosphor is represented by the formula ASUBx/SUBBSUB4-2x/SUBOSUB6-2x/SUB:MnSUBy/SUB, wherein A is Mg, Zn, Ca, or Li, B is Al or Ga, 0.6=x=1.4, and 0.01=y=0.1. The phosphor has excellent brightness, color purity, and discharging characteristics, and a short decay time. In one embodiment, the phosphor has a stable spinel structure, and is stable with regard to external influence such as heat, ion bombardment, and vacuum ultraviolet rays. Longer-lived light-emitting devices are also disclosed.
