Copper-Based Material Could Lead to Inexpensive, High-Yield OLEDs

Facebook Twitter LinkedIn Email Comments
At the Paul Scherrer Institute (PSI), researchers have discovered a green luminescent substance that could enable OLEDs to deliver high light yields inexpensively and on a large scale. Many of the materials that have been considered for OLEDs contain expensive additives such as iridium, making their large-scale application impractical. The researchers at PSI turned to the copper-containing compound CuPCP. Copper is a relatively inexpensive metal, and the compound CuPCP can be easily produced in large quantities. CuPCP gives off an intense green glow not only when current is...Read full article
