LONDON, March 26 -- High-efficiency organic light-emitting diodes (OLEDs) using pioneering dendrimer materials have been developed by scientists sponsored by display technology developer Opsys, which says the results have broad implications for the commercialization of OLED technology in the flat-panel display industry. The Opsys-sponsored teams, led by Paul Burn of the University of Oxford and Ifor Samuel at the University of St. Andrews, have shown that dendrimers can be used to produce efficient solution-processed OLED devices with just a single layer of organic material between the...Read full articleRelated content from Photonics MediaArticlesLight-matter Discovery Challenges Understanding of Photon MomentaAlthough bulk silicon does not naturally emit light, silicon that is porous and nanostructured can produce detectable light after being exposed to visible radiation.
