Abstract

A nano-crystal diamond film synthesized on a substrate and containing, as a major component, nano-crystal diamond having a grain diameter from 1 nm to less than 1000 nm. This nano-crystal diamond film can be formed on a substrate by means of a plasma CVD method using a raw material gas containing a hydrocarbon and hydrogen, allowing the formation of the nano-crystal diamond film to take place outside the plasma region. This nano-crystal diamond film is applicable to the manufacture of an electrochemical device, an electrochemical electrode, a DNA chip, an organic electroluminescent device, an organic photoelectric receiving device, an organic thin film transistor, a cold electron-emission device, a fuel cell and a catalyst.
