Luminescent carbon dots provide nontoxic alternative to silicon

Facebook Twitter LinkedIn Email
Noting the toxicity and potential environmental hazard of silicon-based semiconductor quantum dots, researchers at Clemson University in South Carolina have created carbon nanodots with photoluminescence that is dependent upon particle size and surface passivation. Silicon nanostructures are strongly luminescent when their surfaces are oxidized, and the researchers, led by chemistry professor Ya-Ping Sun, theorized that carbon would act similarly. They report in the May 23 ASAP edition of the Journal of the American Chemical Society that, to test this, they used a Q-switched Nd:YAG laser...Read full article
