Light emitting diodes hold the potential to drastically improve the energy efficiency of lighting our homes and workplaces. Conventional LEDs produce light only at specific wavelengths. Making white light from them is costly. Now a potentially cheaper option is emerging thanks to the development of organic dyes that emit blue and amber photons, and the ability to combine both in the light-emitting layer of an LED. The result is an organic LED (WOLED) that produces white light directly.
