Abstract	Carbon inverse opals with three-dimensional nanoporous structures are fabricated by a template method using synthetic opals formed by the sedimentation of SiO2 spheres. The pore size of the carbon inverse opals ranges widely from about 74 nm to 550 nm depending on the diameter of the SiO2 spheres. These nanoporous structures of carbon exhibit excellent characteristics as electron emitters. As the pore size of porous carbon decreases, the effective emission area of field emission increases. The main emitter sites of porous carbon are interpreted to be the edges formed in the boundary of the neighboring pores. The emission characteristics have drastically improved upon heat treatment at high temperatures (about 2760 ℃). The authors would like to express sincere thanks to Dr. T. Nakayama and Professor K. Niihara for the use of facilities of the electron microscopy.
