Impact of Erbium-doped silicon nanocrystals on the properties of polyphenylene vinylene films

The fabrication and properties of composite films composed of poly(phenylene vinylene) (PPV) and Erbium(Er)-doped silicon (Si) Nan crystals are presented. The presence of Er-doped Si nanoparticles in the film are found strongly impacting the steady-state photoluminescence of the PPV, while the presence or absence of solvent chosen for the nanocrystals influence the carrier transport and resultant visible electroluminescence of light-emitting diodes fabricated from these materials.
