Abstract
An electron emission source includes nano-sized acicular materials and a cracked portion formed in at least one portion of the electron emission source. The acicular materials are exposed between inner walls of the cracked portion. A method for preparing the electron emission source, a field emission device including the electron emission source, and a composition for forming the electron emission source are also provided in the present invention.
Claims8
An electron emission source, comprising:
- an organic residue;
- where the organic residue is formed by crosslinking an organic moiety, the organic moiety comprising an acrylate-based oligomer and a (meth)acryl-based monomer;
- a cracked portion formed in at least one portion of the electron emission source;
- and,
- nano-sized acicular materials exposed within the cracked portion, wherein one end or opposite ends of each of the nano-sized acicular materials are fixed on an inner wall of the cracked portion, wherein an amount of the organic residue on a surface of the nano-sized acicular materials exposed within the cracked portion is about 0.1 parts by weight or less based on a total weight of 100 parts by weight of the nano-sized acicular materials.
