RED PHOSPHOR AND METHOD OF PREPARING THE SAME

摘要

Provided is a red phosphor which is excellent in emission efficiency by a long wavelength UV excitation source and has a fine and uniform particle size. The red phosphor includes a compound represented by (Li.sub.(2-z)-xM.sub.x)(AO.sub.4).sub.y:Eu.sub.z,Sm.sub.q and a flux wherein M is K, Mg, Na, Ca, Sr, or Ba, A is Mo or W, 0.ltoreq.x.ltoreq.2, 0.5.ltoreq.y.ltoreq.5, 0.01.ltoreq.z.ltoreq.1.5, and 0.001.ltoreq.q.ltoreq.1.0. Provided is also a method of preparing the red phosphor.
