Anodic electrochemiluminescence from CsPbBr3 perovskite quantum dots for an alkaline phosphatase assay.

The ability to use ascorbic acid as a co-reactant to induce anodic electrochemiluminescence of CsPbBr3 perovskite quantum dots was investigated and observed in aqueous medium for the first time. Benefiting from its glorious anodic electrochemiluminescence emission, an ascorbic-acid-responsive electrochemiluminescence system was developed to detect alkaline phosphatase.
