Abstract: An optical film includes a transparent substrate, an optical material comprising quantum dots disposed over a surface of the substrate, and a light diffusion film disposed over the optical material, the light diffusion film including a transparent support and a diffusion layer formed over the transparent support, the light diffusion film being positioned such that the transparent support is between the optical material and the diffusion layer, the light diffusion film having a back to front haze value of at least 80% and a total back to front light transmission value of at least 50%. Other layers can optionally be included in the optical film. A backlight unit and display including the optical film taught herein are also disclosed.

Abstract: A method of processing quantum dots is disclosed. The method comprises applying energy to excite the quantum dots to emit light and placing the quantum dots under vacuum after excitation of the quantum dots. Also disclosed is a method of processing a component including quantum dots comprising applying energy to the component including quantum dots to excite the quantum dots to emit light; and placing the component including quantum dots under vacuum after excitation. A method for processing a device is further disclosed, the method comprising applying energy to the device to excite the quantum dots to emit light; and placing the device under vacuum after excitation of the quantum dots. A method for preparing a device is also disclosed. Quantum dots, component, and devices of the methods are also disclosed.
