Synthesis of yellow fluorescent carbon dots and their application to the determination of chromium(III) with selectivity improved by pH tuning
Carbon dots with yellow fluorescence (y-CDs) were synthesized from sucrose by acid carbonization with phosphoric acid as the dehydrating agent. Optimal yield was obtained by heating sucrose in concentrated pho...

Detection of Sn(II) ions via quenching of the fluorescence of carbon nanodots
We report that fluorescent carbon nanodots (C-dots) can act as an optical probe for quantifying Sn(II) ions in aqueous solution. C-dots are synthesized by carbonization and surface oxidation of preformed sago ...
