Abstract
Quantum dot layers and display devices including quantum dot layers are described. In an embodiment the quantum dot layer includes quantum dots with coatings to adjust the spacing between adjacent quantum dots. In an embodiment, the coatings are metal oxide coatings and may create a charge transporting matrix. In an embodiment, the coatings are core-material coatings. The QD layers may be QD-LED compatible.
