A recent story in the journal Advanced Materials, details advances in the use of organic light-emitting diodes (OLEDs) by Ghassan Jabbour and Jian Li, with help from graduate students Evan Williams and Kirsi Haavisto, a Fulbright scholar from Finland.

These researchers have developed an organic lighting device with “100 percent internal quantum efficiency” by employing newly designed host materials coupled with optimized device architecture.

“There is no waste of electricity,” Jabbour says. “All the current you are putting into the device is being used to produce light. It's the first time something like this has been demonstrated. Nobody else has shown a 100 percent internal quantum efficiency for lighting devices using a single molecular dopant to emit white light.”
