Radically different OLEDs break the aufbau principle
Organic radical-based materials could keep next generation displays from dimming over time
UK Researchers have developed a new kind of organic light-emitting-diode (OLED) based on organic radicals that violate the aufbau principle ,1 which states that electrons fill up atomic orbitals from lowest to highest energy. The discovery could enable the manufacture of OLEDs that stay brighter for longer.
