An improved ligand-assisted reprecipitation method to synthesize aqueous-phase CsPbBr3 perovskite nanocrystals and investigate their electrochemiluminescence behavior

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.
