Phosphors, fabricating method thereof, and light emitting device employing the same
A phosphor material is provided which having the chemical formula is (Ln1-x-y-zCex)3Al5O12-y-zCyNz, wherein Ln is one or more metals selected from Y, La, Pr, Nd, Eu, Gd, Tb, Dy, Yb, Er, Sc, Mn, Zn, Cu, Ni and Lu, and 0.01≦x≦0.3, 0≦y≦0.3, and 0.001≦z≦0.3. Before the sintering process with high temperature is performed, the different kinds of nitrogen source or the combination of nitrogen source and carbon source thereof is added into the synthesized phosphor to provide carbon atom (C) and nitrogen atom (N) that is doped into the phosphor material, in which the nitrogen source includes an organic and an inorganic nitrogen compound. The nitrogen source is added in addition to substitute oxygen atom and to perform doping process.
