Abstract
A method of making a device comprises forming a layer comprising quantum dots over a substrate including a first electrode, fixing the layer comprising quantum dots formed over the substrate, and exposing at least a portion of, and preferably all, exposed surfaces of the fixed layer comprising quantum dots to small molecules. The layer comprising quantum dots can be preferably fixed in the absence or substantial absence of oxygen. Also disclosed is a method of making a device comprises forming a layer comprising quantum dots over a substrate including a first electrode, exposing the layer comprising quantum dots to small molecules and light flux. Also disclosed is a method of making a film including a layer comprising quantum dots, the method comprising forming a layer comprising quantum dots over a carrier substrate, fixing the layer comprising quantum dots formed over the carrier substrate, and exposing at least a portion of, and preferably all, exposed surfaces of the fixed layer comprising quantum dots to small molecules. The layer comprising quantum dots can be preferably fixed in the absence or substantial absence of oxygen. Also disclosed is a method of preparing a device component including a layer comprising quantum dots, the method comprising forming a layer comprising quantum dots over a layer comprising a charge transport material, exposing the layer comprising quantum dots to small molecules and light flux. Devices, device components, and films are also disclosed.
