Phosphors capable of improving stability to moisture include silicate-based phosphor particles and coating layers. The coating layer is formed on the surface of the phosphor particles and includes a metal oxide. Such a phosphor is first mixed with a precursor of a metal oxide, a solvent, a phosphor and water to form a coating layer containing a metal oxide on the surface of the phosphor, and then separated by drying the phosphor formed with a coating layer, and then dried phosphor It is prepared by heat treatment. As a result, the phosphor may be prevented from reacting with water to improve stability to water. |
