Caption: A sample of the yellowish-colored, platinum-rich polymer known as Pt-1, emits light as a laser beam hits it at a University of Utah physics laboratory. The light appears white because the polymer emits a combination of broad-spectrum violet and yellow, which combine to appear white. The polymer and its relatives hold promise for use in a new generation of organic light-emitting diodes, or OLEDs, which could produce white light for more efficient LED light bulbs of the future.
