COMPOSITION FOR PREPARING EMITTER, METHOD OF PREPARING THE EMITTER USING THE COMPOSITION, EMITTER PREPARED USING THE METHOD AND ELECTRON EMISSION DEVICE INCLUDING THE EMITTER |
摘要 |
A composition for preparing an emitter including: flake type carbide-derived carbon which is prepared by thermochemically reacting carbide compounds with halogen-containing gases to extract all elements of the carbide compounds except carbon, an organic solvent and a dispersant. A method of preparing the emitter using the composition for forming the emitter, an emitter prepared using the method and an electron emission device. The emitter has good uniformity and a long lifetime. It can be prepared using a more inexpensive method than using conventional carbon nanotubes. A pattern can be formed by easily regulating the size of the manufactured emitter using an ink jet printer. Non-uniform emission generated by residue when using a conventional printing method can be avoided. Thus, a micro electrode, in which an arc discharge does not occur even in the presence of a strong electric field, can be conveniently manufactured.
