摘要： A luminescent component comprises a first film comprising a first solid polymer composition and a second film comprising a second solid polymer composition. The first solid polymer composition comprises first luminescent crystals. The second solid polymer composition comprises second luminescent crystals. The first luminescent crystals are of size between 3 nm and 3000 nm, and emit red light in response to excitation by light with a shorter wavelength. The second luminescent crystals are of size between 3 nm and 3000 nm, and emit green light in response to excitation by light with a shorter wavelength. Said luminescent component is particularly suited for the application in LCD-backlight color conversion.

摘要： In certain embodiments, a first semiconductor material is vaporized to generate a vapor phase condensate. The vapor phase condensate is allowed to form nanoparticles. The nanoparticles are annealed to yield nanoparticles or cores. The cores are overcoated by introducing a solution containing second semiconductor material precursors in a coordinating solvent into a suspension of cores at a desired elevated temperature and mixing for a period of time sufficient to cause diffusion of the shell into the core. The diffusion of the shell into the core causes the quantum dots to exhibit a broadened optical emission. The produced quantum dots may be incorporated into a quantum dot based radiation source.
