Abstract
A composition useful for altering the wavelength of visible or invisible light is disclosed. The composition comprising a solid host material and quantum confined semiconductor nanoparticles, wherein the nanoparticles are included in the composition in amount in the range from about 0.001 to about 15 weight percent based on the weight of the host material. The composition can further include scatterers. An optical component including a waveguide component and quantum confined semiconductor nanoparticles is also disclosed. A device including an optical component is disclosed. A system including an optical component including a waveguide component and quantum confined semiconductor nanoparticles and a light source optically coupled to the waveguide component is also disclosed. A decal, kit, ink composition, and method are also disclosed. A TFEL including quantum confined semiconductor nanoparticles on a surface thereof is also disclosed.
