Y.‐J. Pu, J. Kido, and co‐workers show on page 1327 the first report on multiorganic light‐emitting devices comprising two light‐emitting units stacked in series through a charge‐generation layer, fabricated by solution processes. A zinc oxide nanoparticle/polyethyleneimine bilayer is used as the electron‐injection layer and phosphomolybdic acid is used as the charge‐generation layer. Appropriate choice of solvents during spin‐coating of each layer ensures a nine‐layered structure.
