Chlorine -- it's not just for keeping your clothes white and your pool clean anymore! Soon, layers of the stuff, just a single atom thick, could play a pivotal role in OLED manufacturing. Researchers at the University of Toronto have found that this tiny amount of Cl can almost double the efficiency of existing displays while reducing complexity and driving down costs. Using a rather simple procedure involving UV light, the team was able to chlorinate standard electrode panels found in conventional OLEDs without having toxic chlorine gas wafting about. Wh
