• We propose a novel ligand-assisted reprecipitation method to synthesize aqueous-phase CsPbBr 3 nanocrystals, the fluorescence intensity of which remained at 51% after 120 h. As a multifunctional additive, cesium trifluoroacetate (Cs-TFA) can improve the surface adsorption energy and induce nanocrystals to show significant anodic electrochemiluminescence (ECL) and stable cathodic ECL performances. A novel approach is proposed to prepare aqueous-phase CsPbBr 3 nanocrystals by employing a multifunctional additive (cesium trifluoroacetate), and the nanocrystals exhibit apparent anodic and cathodic ECL redox properties and responses in an air-saturated aqueous medium.
