Abstract
An organic device has a hole current-electron current conversion layer which comprises a laminate of an electron transportation section and a hole transportation section. The electron transportation section includes a charge transfer complex formed upon an oxidation-reduction reaction between a reduced low work function metal and an electron-accepting organic compound, the reduced metal being produced upon an in-situ thermal reduction reaction caused upon contact, through lamination or mixing by co-deposition, of an organic metal complex compound or an inorganic compound containing at least one metal ion selected from ions of low work function metals having a work function of not more than 4.0 eV, and a thermally reducible metal capable of reducing a metal ion contained in the organic metal complex compound or the inorganic compound in vacuum to the corresponding metal state, and the electron transportation section having the electron-accepting organic compound in the state of radical anions. The hole transportation section includes an organic compound having an ionization potential of less than 5.7 eV and an electron-donating property and an inorganic or organic substance capable …
