    摘要： A method of coating phosphor powder with a composite oxide, and a light emitting device that employs the phosphor powder coated with the composite oxide are disclosed. The method includes mixing a silicon oxide precursor and a precursor of another oxide in water and alcohol to form a primary coating layer on a sulfide phosphor through a sol-gel reaction, heat treating the primary coating layer to form a composite oxide layer of the silicon oxide and the other oxide from the primary coating layer. The method improves moisture stability of the sulfide phosphor compared to a sulfide phosphor coated with a single silicon oxide film.

    摘要： A phosphor is formed with a glass coating layer on a surface of a phosphor grain to have improved moisture and/or thermal stability. A method for manufacturing the phosphor comprises preparing phosphor gains excitable by light, and forming a glass coating layer on a surface of each phosphor grain. The glass coating layer may be formed by mixing the phosphor grains with a glass composition; heat-treating a mixture of the phosphor grains and the glass composition to make the glass composition melt and surround the phosphor grains; and cooling and breaking the heat-treated mixture to provide phosphors, each comprising the phosphor grain having the glass coating layer formed on a surface of the phosphor grain.
