Toward a Truly White Organic LED



UTAH PHYSICISTS DEVELOP POLYMER WITH TUNABLE COLORS

By inserting platinum atoms into an organic semiconductor, University of Utah physicists were able to “tune” the plastic-like polymer to emit light of different colors – a step toward more efficient, less expensive and truly white organic LEDs for light bulbs of the future.

“These new, platinum-rich polymers hold promise for white organic light-emitting diodes and new kinds of more efficient solar cells,” says University of Utah physicist Z. Valy Vardeny, who led a study of the polymers published online Friday, Sept. 13 in the journal Scientific Reports.
