摘要： The present invention relates to a phosphor that can be excited by UV3 purple or blue light LED, its production and the light emitting devices. General formula of the phosphor is Ln a M b (O,F) 12 :(R 3+ , M '2+ ) x, wherein, Ln is at least one metal element selected from a group consisting of Sc, Y, La, Pr, Nd, Gd, Ho, Yb and Sm, 2.6≤ a≤3.4; M is at least one element selected from a group consisting of B, Al and Ga, 4.5≤b≤5.5; R is at least one metal element selected from a group consisting of Ce and Tb; M' is at least one metal element selected from a group consisting of Ca, Sr, Ba, Mn and Zn, 0.001≤x≤0.4. Production method of the phosphor is: raw materials are weighed according to general formula. Further, flux is added. The raw materials are mixed, grinded sequentially and then baked at high temperature in reducing atmosphere. After post-treatment, the phosphor of the present invention is obtained. The phosphor possess broad emitting range, high efficiency, better uniformity and stability. The production method is simple, no pollution and lower cost. A light emitting device can be obtained by incorporating this phosphor into a UV, purple or blue light emitting device.
