In work that could help to solve the challenge of finding blue light sources matching the performance of red and green ones for displays using organic light-emitting diodes, researchers have demonstrated devices that produce pure-blue emission with high efficiency, maintain brightness for relatively long times, and lack any expensive metal atoms -- a set of properties that has so far been difficult to obtain simultaneously.
