摘要

A component including a substrate, at least one layer including a color conversion material including quantum dots disposed over the substrate, and a layer including a conductive material (e.g., indium-tin-oxide) disposed over the at least one layer. (Embodiments of such component are also referred to herein as a QD light-enhancement substrate (QD-LES).) In certain preferred embodiments, the substrate is transparent to light, for example, visible light, ultraviolet light, and/or infrared radiation. In certain embodiments, the substrate is flexible. In certain embodiments, the substrate includes an outcoupling element (e.g., a microlens array). A film including a color conversion material including quantum dots and a conductive material is also provided. In certain embodiments, a component includes a film described herein. Lighting devices are also provided. In certain embodiments, a lighting device includes a film described herein. In certain embodiments, a lighting device includes a component described herein.

說明書

In certain embodiments, a lighting device includes a component comprising a substrate SUB comprising a material that is transparent to light within a predetermined range of wavelengths, a layer comprising a predetermined arrangement of features disposed over a predetermined region of a surface of the substrate SUB, wherein at least a portion of the features comprise a color conversion material CCM comprising quantum dots, and a conductive material disposed over at least a portion of the layer, the conductive material being transparent to light within a second predetermined range of wavelengths, the conductive material forming a first electrode ELT1 of the device; an emissive layer EML disposed over at least a portion of the conductive material, wherein the emissive layer EML comprises a material capable of emitting light; and a second electrode ELT2 disposed over the emissive layer.
