Communication: Inorganic nanoparticles ira 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 originates most probably from the nanoparticles alone. The role of the PPV is discussed.
