CATALYST COMPOSITION FOR FORMING CARBON-BASED NANO MATERIAL, CARBON-BASED NANO MATERIAL DEVICE, CATHODE SUBSTRATE FOR ELECTRON DISCHARGING ELEMENT AND ITS MANUFACTURING METHOD, AND ELECTRON DISCHARGING ELEMENT DEVICE AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a catalyst composition for forming a carbon-based nano material on a glass substrate at a low temperature, to provide a cathode substrate provided with the carbon-based nano material formed by using the catalyst composition and its manufacturing method, and to provide an electron discharging element device using the cathode substrate and its manufacturing method.;SOLUTION: The catalyst composition includes a first metal functioning as a catalyst which is at least one kind of metal selected from Fe, Ni and Co, or its alloy, a second metal which is at least one kind of metal selected from Cr, Mo, W, Nb, Ta and V, or its alloy, and nitrogen or a nitrogen compound. The cathode substrate is provided with the carbon-based nano material formed by using the catalyst compound. The carbon-based nono material device uses the substrate.;COPYRIGHT: (C)2008,JPO&INPIT
