Fe<sup>3+</sup>-induced luminescence quenching in carbon dots – mechanism unveiled
Varsha Raveendran, C. Anjali, N.K. Renuka
Abstract
-induced luminescence quenching was partially restored in the presence of ascorbic acid, enabling the sub-micromolar level monitoring of this analyte, with the lowest detection amount of 276 nM. Turnbull's blue method is adopted for confirming the reducing role of ascorbic acid, which eventually increased the luminescence of the system, evoking a turn-on response.
