Abstract
A light-emissive device includes a substrate having a first electrode formed on the substrate. A colloidal light-emitting layer comprising inorganic, light-emissive particles is formed over the first electrode. A second electrode is formed over the light-emitting layer. At least one of the first and second electrodes is transparent. The transparent electrode preferably has a refractive index substantially equal to or greater than the refractive index of the colloidal light-emitting layer. Finally, a light-scattering layer is formed on a side of the transparent electrode opposite the colloidal light-emitting layer.
