| 摘要 |
The present invention describes a solventless ligand exchange using a siloxane polymer having a binding ligand that displaces the binding ligand on a quantum dot material. High performance down-converting phosphor technologies will play a prominent role in the next generation of visible light emission, including high efficiency solid-state white lighting. In addition, such technologies are also applicable to near infrared and infrared light emitting technologies. Down-conversion from ultraviolet or blue light emitting semiconductor light emitting diodes into blue, red and green wavelengths offers a fast, efficient and cost-effective path for delivering commercially attractive white light sources. Unfortunately, existing rare-earth activated phosphors or halophosphates, which are currently the primary source for solid-state down-conversion, were originally developed for use in fluorescent lamps and cathode ray tubes, and therefore have a number of critical shortfalls. |
