Abstract
A voltage driven light emitting device includes an electroluminescent material and semiconductor nanocrystals, luminescent organic small molecules, mixtures of emissive species molecules, or conductive polymers. The semiconductor nanocrystals, luminescent organic small molecules, mixtures of emissive species molecules, or conductive polymers emit light. The semiconductor nanocrystals, luminescent organic small molecules, mixtures of emissive species molecules, or conductive polymers can be doped to provide desired emission characteristics. Devices that share a substrate and emit more than one color may be conveniently made.
