Phosphor, method for manufacturing same, and light emitting diode |
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 grains 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.
