Quantum dot light enhancement substrate and lighting device including same
摘要
說明書
In certain embodiments, a film comprises a conductive material and a plurality of features comprising a color conversion material CCM disposed over at least a portion of the conductive material, wherein the color conversion material CCM comprises quantum dots and wherein the color conversion material CCM included in each of the features is selected to include quantum dots capable of emitting light having a predetermined wavelength such that the film is capable of emitting light of a preselected color when optically coupled to a source of light emission.
In certain embodiments, the preselected color is white.
In certain embodiments, film comprises a layered arrangement of two or more layers comprising color conversion material CCM, wherein color conversion material CCM includes quantum dots and wherein the color conversion material CCM included in each layer is selected to include quantum dots capable of emitting light having a predetermined wavelength such that the film is capable of emitting light of a preselected color when optically coupled to source of light emission. In certain embodiments, layers are arranged in order of decreasing or increasing wavelength.
In accordance with another embodiment of the present invention, there is provided a component comprising a substrate SUB comprising a material that is transparent to light within a predetermined range of wavelengths, a color conversion material CCM comprising quantum dots disposed over a predetermined region of a surface of the substrate SUB, and a conductive material disposed over at least a portion of the color conversion material CCM, the conductive material being transparent to light within a second predetermined range of wavelengths.
In certain embodiments, the quantum dots comprise semiconductor nanocrystals.
