Determination of l-ascorbic acid in human serum by chemiluminescence based on hydrogen peroxide–sodium hydrogen carbonate–CdSe/CdS quantum dots system

In the present work, a strongly chemiluminescence (CL) from the mixing of hydrogen peroxide (H 2O 2), hydrogen carbonate (HCO 3 −) and CdSe/CdS quantum dots (QDs) was observed. The addition of trace amount of l-ascorbic acid into the CL system caused significant quenching luminescence intensity. Bas...
