Abstract
A lighting system including a light source capable of generating light, and an optical component optically coupled to receive at least a portion of the light generated by the light source and convert at least a portion of the light so received to a predetermined wavelength such that the light emitted by the lighting system includes light emission from the light source supplemented with light emission at the predetermined wavelength, wherein the optical component including an optical material comprises quantum confined semiconductor nanoparticles. Also disclosed is an optical component comprising a light guide plate and an optical material disposed over at least a portion of a surface of the light guide plate, the optical material comprising quantum confined semiconductor nanoparticles capable of emitting light in a predetermined spectral region. Devices are also disclosed.
