Abstract: Disclosed are a method of manufacturing a metal plate with a luminous property, and a plate manufactured by the same. The method of manufacturing the metal plate according to the present invention includes the steps of: carrying a metal plate by an opposite electrode and one electrode in an electrolyte solution containing rare-earth metal precursors; applying electricity to the electrode to form an oxidized layer and a plurality of voids on the surface of the metal plate while the opposite electrode and the one electrode are spaced apart from each other; and reducing the rare-earth metal by the oxidized layer and the voids. Therefore, the corrosion resistance or friction resistance of the metal material is improved, and the luminous property is improved.

Abstract: PURPOSE: A method for manufacturing nitride phosphors using a spark plasma sintering method is provided to obtain faster reaction time than a gas pressure sintering method, to economically manufacture the nitride phosphors at low nitrogen pressure(or a vacuum condition), and to prevent carbon contamination. CONSTITUTION: A method for manufacturing nitride phosphors uses an electric discharge plasma sintering apparatus including a carbon mold(22) and first and second carbon punches(23,24). The method comprises the following steps: providing a phosphor powder material(21) including nitride powder and an activator; coating a part of a carbon film with boron nitride; arranging the carbon film along the inner wall of the carbon mold and putting the phosphor powder material into the carbon mold; installing the carbon mold in a chamber of the electric discharge plasma sintering apparatus and removing oxygen from the chamber; sintering the phosphor powder material mixture by pressurizing the mixture; and obtaining phosphor powder by pulverizing the sintered material.
