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.
