Light strips for lighting and backlighting applications

摘要

Light strips for emergency lighting, path lighting, accent lighting and device lighting are provided. Devices incorporating and lighted by the light strips are also provided. The light strips include a light emitting layer made from a plurality of semiconductor nanoparticles disposed between and in electrical communication with an anode and a cathode. The semiconductor nanoparticles may be made from Group IV semiconductors, such as silicon. Devices that may be lit with the light strips include displays and keypad, such as those found in cellular phones and personal digital assistants.
