Abstract

Quantum dot light emitting diodes (QD-LEDs) are formed that are transparent and emit light from the top and bottom faces. At least one electrode of the QD-LEDs is a dielectric/metal/dielectric layered structure, where the first dielectric comprises metal oxide nanoparticles or polymer-nanoparticle blends and is 10 to 40 nm in thickness, the metal layer is 5 to 25 nm in thickness, and the second dielectric layer is a nanoparticulate, polymer-nanoparticle blend or continuous layer of 30 to 200 nm in thickness and is situated distal to the light emitting layer of the QD-LED.
