Abstract:
1. A light-emissive device comprising: a substrate; a first electrode formed on the substrate; a colloidal light-emitting layer comprising inorganic, light-emissive particles formed over the first electrode; a second electrode formed over the colloidal light-emitting layer; wherein the first electrode is transparent and has a refractive index substantially equal to or greater than the refractive index of the colloidal light-emitting layer; a light-scattering layer formed on a side of the transparent electrode opposite the colloidal light-emitting layer, and wherein the second electrode comprises a transparent, conductive layer and a reflective conductive layer having a conductivity greater than the transparent conductive layer, and wherein the light-scattering layer is formed on only a first portion of the transparent conductive layer between the transparent conductive layer and the reflective conductive layer, and the reflective conductive layer is in electrical contact with the transparent conductive layer in a second portion of the transparent conductive layer.
