Abstract: A phosphor composition contains phosphor particles and a water-soluble rare earth compound uniformly covering the surfaces of the phosphor particles. The rare earth compound is present in an amount of from 0.001 to 5% by weight in terms of the corresponding rare earth oxide, based on the weight of the phosphor particles.
