Rand develops new LED lighting technology with self-assembling particles

January 23, 2017

Prof. Barry Rand, postdoctoral researcher Zhengguo Xiao and Graduates Student Ross Kerner and Lianfeng Zhao have developed new LED technology by refining the manufacturing of light sources made with crystalline substances known as perovskites, a more efficient and potentially lower-cost alternative to materials used in LEDs found on store shelves.
 
The researchers developed a technique in which nanoscale perovskite particles self-assemble to produce more efficient, stable and durable perovskite-based LEDs. This technique could speed the use of perovskite technologies in commercial applications such as lighting, lasers and television and computer screens.  More details can be found here.
