Organic Light-Emitting Diode (IMAGE) University of Utah Caption An organic light-emitting diode, or OLED, glows orange when electrical current flows through it. University of Utah physicists used this kind of OLED -- basically a plastic LED instead of a conventional silicon semiconductor LED -- to show that they could read the subatomic 'spins' in the center or nuclei of hydrogen isotopes and use those spins to control current to the OLED. It is a step toward 'spintronic' devices such as faster computers, better data storage and more efficient OLEDs for TV, computer and cell phone displays.
