‘Quantum dot’ lighting technology takes forward leap thanks to new superacid treatment

A “superacid” much stronger than automobile battery acid has enabled a key advance toward a new generation of LED lighting that’s safer, less expensive and more user friendly. Researchers at Oregon State University used the organic superacid to improve the performance of “quantum dots” made from copper indium disulfide, a compound much less toxic than the lead or cadmium that typically serve as the basis for the light-emitting nanocrystals. Used in optics and electronics, quantum dots have been around for s
