Abstract

Carbon dots, thanks to their surface functional groups are able to coordinate Eu(III) ions sensitizing the luminescence coming from the lanthanide excited states. We prepared C-dots from solid olive waste, and assembled them in a new CDs-Eu(III) complex, in aqueous solution. The new species is able to transduce the presence of protons into a dual optical signal working as H+-sensor in the 6–2 pH range.
