Abstract
An example quantum dot (QD) device comprises a QD layer on a substrate, and may be fabricated by aerosol deposition, for example by mist deposition. An example approach includes providing a liquid precursor including QDs dispersed in a liquid carrier, generating a mist of droplets of the liquid precursor, directing the droplets towards the substrate so as to form a liquid precursor film on the substrate, and removing the liquid carrier from the liquid precursor film to form the quantum dot layer on the substrate. Example devices include multi-color QD-LED (light emitting diode) displays, and other devices.
