Molecular makeover brightens organic light near 1,000 nanometers

Near-infrared organic light-emitting diodes (OLEDs) that emit about 1,000 nanometers could support biomedical and security technologies. Yet pushing organic light to these longer wavelengths usually causes a steep drop in efficiency. As the energy gap becomes smaller, molecular vibrations more readily turn excited-state energy into heat rather than light.
