Abstract
The fabrication and characterisation of solution-processed, all-inorganic light-emitting devices incorporating colloidal CdSe/ZnS quantum dots are presented. Using sol–gel synthetic routes, highly luminescent core–shell QDs are embedded between spin-coated p-type NiO and n-type ZnO charge-transport layers. The resulting devices show pure QD electroluminescent emissions with a maximum EL brightness of 249 cd m−2.Keywords
