White-light LED red phosphor and method of manufacturing the same

摘要

A white-light LED red phosphor and method of manufacturing the same are provided. The luminescent materials are represented by the general formula: Ca_1-y-m-e-rY_yM_mX_x-pP_pZ_zN_n:Eu_e, R_f, wherein M is at least one selected from Sr, Ba, Sc, Li, Na and K; X is at least one selected from B, Al and Ga, and Al must be contained; Z is at least one selected from Si, V and Nb, and Si must be contained; R is at least one selected from Dy, Er, Tm and Lu, and Dy must be contained; 0.001≦y≦0.2, 0.001≦m≦0.2, 0.5≦x≦1.5, 0.5≦z≦1.5, 0.001≦p≦0.1, 2≦n≦4, 0.001≦e≦0.2 and 0.001≦r≦0.1. The phosphor according to the present invention has features such as good chemical stability, high luminous efficiency, and good anti-luminous attenuation performance, etc.
