The present invention relates to flexible devices including semiconductor nanocrystals, arrays including such devices, systems including the foregoing, and related methods. In one embodiment, a flexible light-emitting device includes a flexible substrate including a first electrode, an emissive layer comprising semiconductor nanocrystals disposed over the substrate, and second electrode disposed over the emissive layer comprising semiconductor nanocrystals, wherein, when the device is curved, the emissive layer comprising semiconductor nanocrystals lies substantially in the neutral plane of the device. In another embodiment, a light-emitting device includes an emissive layer comprising semiconductor nanocrystals disposed between two flexible substrates, a first electrode disposed over the emissive layer comprising semiconductor nanocrystals, and a second electrode disposed under the emissive layer comprising semiconductor nanocrystals. In certain preferred embodiments, at least one charge transport layer is disposed between one of the electrodes and the layer comprising semiconductor nanocrystals.
A flexible light-emitting device including an emissive layer formed of one or more distinct layers of inorganic semiconductor nanocrystals disposed between two flexible substrates, wherein the emissive layer does not include a matrix material, a first electrode disposed over the emissive layer and a second electrode disposed under the emissive layer, wherein the moduli of the various parts of the device are such that, when the device is curved, the neutral plane of the device lies substantially in the plane of the emissive layer.
A flexible light-emitting device including:
