    Abstract: The invention pertains to the field of nanotechnology. The disclosure provides nanostructure compositions comprising (a) at least one organic solvent; (b) at least one population of nanostructures comprising a core and at least one shell, wherein the nanostructures comprise inorganic ligands bound to the surface of the nanostructures; and (c) at least one poly(alkylene oxide) additive. The nanostructure compositions comprising at least one poly(alkylene oxide) additive show improved solubility in organic solvents. And, the nanostructure compositions show increased suitability for use in inkjet printing. The disclosure also provides methods of producing emissive layers using the nanostructure compositions.

    Abstract: Embodiments of a display device are described. A display device includes first and second sub-pixels. The first sub-pixel includes a first light source having a quantum dot (QD) film, a blocking layer disposed on the QD film, and a first portion of an organic phosphor film disposed on the blocking layer and a first substrate configured to support the first light source. The blocking layer is configured to prevent emission of light from the first portion of the organic phosphor film and the QD film is configured to emit a primary emission peak wavelength in a red, green, cyan, yellow, or magenta wavelength region of an electromagnetic (EM) spectrum. The second sub-pixel includes a second light source and a second substrate configured to support the second light source. The second light source has a second portion of the organic phosphor film disposed adjacent to the QD film. The second portion of the organic phosphor film is configured to emit a primary emission peak wavelength in a blue, violet, or ultraviolet wavelength region of an EM spectrum.

    Abstract: Embodiments of a device and a method of forming the same are described. The device includes a backlight unit and an image generating unit. The backlight unit includes an optical cavity having a top side, a bottom side, and side walls. The backlight unit further includes an array of light sources coupled to the optical cavity and a quantum dot film positioned within the optical cavity. The quantum dot film is configured to process light received from the array of light sources and the backlight unit is configured to transit the processed light to the image generating unit. The method includes providing an optical cavity having a top side, a bottom side, and side walls. The method further includes coupling an array of light sources to the optical cavity and supporting a quantum dot film within the optical cavity.
