    • PURPOSE: A surface coating of a silicate phosphor containing an organic/inorganic nanocomposite is provided to improve the initial luminance of the phosphor, and to increase the lifetime of the phosphor at the high temperature and humidity. CONSTITUTION: A silicate phosphor is coated with an organic/inorganic nanocomposite on the surface. The organic/inorganic nanocomposite contains the following: a metal oxide selected from the group formed with SiO_2, TiO_2, and MgO; and a polymer selected from the group consisting of polystyrene and polymethylmethacrylate. 0.1~50wt% of organic/inorganic nanocomposite is coated on the phosphor. The average particle diameter of the metal oxide is 3~100 nanometers.
