Claim 0:
1. A diode comprising:
a flexible substrate or a curved substrate;
a first electrode, wherein the electrode is disposed on at least a portion of the flexible substrate or at least a portion of the curved substrate;
an electron injection layer, wherein the electron injection layer is disposed on the first electrode and is in electrical contact with at least the first electrode;
an emission layer comprising a plurality of quantum dots which comprise colloidal quantum dots (CQDs) or solution processed semiconductor nanocrystals, wherein the emission layer is disposed on the electron injection layer and is in electrical contact with at least the electron injection layer;
a hole injection layer, wherein the hole injection layer is disposed on the emission layer and is in electrical contact with at least the emission layer; and
a second electrode, wherein the second electrode is disposed on at least a portion of the hole injection layer and is in electrical contact with at least the hole injection layer, and wherein from one or more or all of the flexible substrate, first electrode, electron injection layer, hole injection layer, or second electrode has 90% or greater or 95% or greater transmission of visible light wavelengths, wherein the visible wavelength is from 400 nm to 700 nm; and
wherein the first electrode or the second electrode comprises a nanowire embedded in a transparent nanoparticle matrix.
