  • Publication number: 20210408419
    Abstract: Embodiments of the present application relate to illumination devices using luminescent nanostructures. An illumination device includes a first conductive layer, a second conductive layer, a hole transport layer, an electron transport layer and a material layer that includes a plurality of luminescent nanostructures. The hole transport layer and the electron transport layer are each disposed between the first conductive layer and the second conductive layer. The material layer is disposed between the hole transport layer and the electron transport layer and includes one or more discontinuities in its thickness such that the hole transport layer and the electron transport layer contact each other at the one or more discontinuities. Resonant energy transfer occurs between the luminescent nanostructures and excitons at the discontinuities.

  • Publication number: 20180119007
    Abstract: Highly luminescent nanostructures, particularly highly luminescent quantum dots, comprising a nanocrystal core and thick shells of ZnSe and ZnS, are provided. The nanostructures may have one or more gradient ZnSexS1-x monolayers between the ZnSe and ZnS shells, wherein the value of x decreases gradually from the interior to the exterior of the nanostructure. Also provided are methods of preparing the nanostructures comprising a high temperature synthesis method. The thick shell nanostructures of the present invention display increased stability and are able to maintain high levels of photoluminescent intensity over long periods of time. Also provided are nanostructures with increased blue light absorption.
