As a new lighting source, white LED has the advantages of small size, high luminous efficiency, en-ergy saving, long life and environmental protection. The red phosphor used for LED doped with rare earth europium ion is an indispensable component material to realize high color rendering index and low color temperature, and the combined LED has good luminescence characteristics and luminous efficiency. Based on the preparation technology and different matrix systems, the preparation methods and advantages and disadvantages of europium-doped red fluorescent ma-terials were analyzed in this paper. According to the different matrix materials and preparation methods, the mechanism of europium-doped red fluorescent materials was discussed, and the ap-plication prospect of europium-doped red luminescent materials was forecasted.
