White‐light electroluminescence from self‐assembled Q‐CdSe/PPV multilayer structures

Abstract

Inorganic nanoparticles in organic/inorganic hybrid devices are expected to have properties of interest for electroluminescence applications. The preparation of films of CdSe nanoparticles and poly(phenylenevinylene), PPV, by means of self‐assembly is presented and photoluminescence and electroluminescence studies of these films are described. It is shown that nearly white‐light emission is achieved from a twenty‐layer film and that the emission orgininates most probably from the nanoparticles alone. The role of the PPV is discussed.
