Description
Chenhan Zhan, Cunjian Lin, Rujun Yang, and a team of co-authors learn to dial the afterglow of organic materials up and down at will. Some materials keep glowing long after the light goes off because they store energy in traps, but setting the depth of those traps precisely had been out of reach.
Their trick is to engineer the energy levels of the host material that cradles the glowing guest. By choosing the host, they tuned trap depth across a wide range without shifting the color of the glow. One pairing glowed deep blue for more than a day and held its stored energy for two weeks at room temperature. Built into a display pixel, such materials could store information, with uses from night tracing to coded messages.
