In 2020, Australian researchers burned discarded human hair into carbon dots for OLEDs; the dots reached 87% quantum yield, and rigid displays hit 700 cd/m

In a remarkable scientific breakthrough, discarded human hair has been converted into luminous carbon dots, now being explored for their application in next-gen OLED display technology. This eco-friendly material promises to revolutionize electronic screens, paving the way for a sustainable digital future. Although tailored for smaller gadgets at this stage, the applications could redefine efficiency in electronics. This study underscores the incredible possibilities within waste utilization for tech innovation.
