    • 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.
    • 一种用于制备发射体的组合物,包括:通过碳化物化合物与含卤素气体热化学反应制备的片状碳化物衍生碳,以提取除碳,有机溶剂和分散剂之外的碳化物化合物的所有元素。 使用用于形成发射体的组合物制备发射体的方法,使用该方法制备的发射体和电子发射装置。 发射体均匀性好,使用寿命长。 它可以使用比使用常规碳纳米管更便宜的方法来制备。 可以通过使用喷墨打印机容易地调节制造的发射器的尺寸来形成图案。 可以避免使用常规印刷方法时残留物产生的不均匀的发光。 因此,即使在存在强电场的情况下也不会发生电弧放电的微电极,可以方便地制造。
