| abstract |
The invention describes an electroluminescent device wherein the device is characterized by a light emitting layer (3) comprising quantum dots. The quantum dots are provided with capping molecules with functional units on the quantum dot surfaces which cause excited state injection into the quantum dots. The capping molecules with functional units comprise electron transport moieties and/or hole transport moieties and/or exciton transport moieties, which cause the injection of electrons, holes, and excitons, respectively, to the core of the quantum dots. |
