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_(2-z)-xM_x)(AO₄)_y:Eu_z,Sm_q and a flux wherein M is K, Mg, Na, Ca, Sr, or Ba, A is Mo or W, 0<=x<=2, 0.5<=y<=5, 0.01<=z<=1.5, and 0.001<=q<=1.0. Provided is also a method of preparing the red phosphor.
