SALT LAKE CITY — University of Utah researchers have devised a test that lets engineers screen potential polymer materials to predict their efficiency as light-emitting diodes before they are fabricated into plastic LEDs. The test could speed high-efficiency plastic LED development, enable brighter LEDs and lengthen the battery life of portable devices using them.
