Tiny fluorescent semiconductor dots, called quantum dots, are useful in a variety of health and electronic technologies but are made of toxic, expensive metals. Nontoxic and economic carbon-based dots are easy to produce, but they emit less light.
A new study that uses ultrafast nanometric imaging found good and bad emitters among populations of carbon dots. This observation suggests that
