摘要 |
There is provided a fluoride phosphor composite including: fluoride phosphor core particles that may be expressed by the empirical formula AxMFy:Mn4+, wherein A may be at least one selected from the group consisting of Li, Na, K, Rb, and Cs, M may be at least one selected from the group consisting of Si, Ti, Zr, Hf, Ge, and Sn, the composition ratio (x) of A may satisfy 2≦x≦3, the composition ratio (y) of F may satisfy 4≦y≦7, each fluoride phosphor composite particle may be coated with a Mn-free fluoride coating. The Mn-free fluoride coating may have a thickness less than or equal to 35% of the size of each fluoride phosphor composite particle. |
