New 'radical' approach may lead to brighter LEDs

Semiconducting molecules with unpaired electrons, termed 'radicals', can be used to develop very efficient organic-light-emitting diodes (OLEDs), scientists say. The new approach, described in the journal Nature, exploits the quantum mechanical 'spin' property to overcome efficiency limitations for traditional, non-radical materials. Radicals are usually noted for their high chemical reactivity and often detrimental effects, from human health to the ozone layer.
