We report cathodic electrochemiluminescence (ECL) from all-inorganic perovskite nanocrystals (NCs) in an aqueous medium. An electron transfer annihilation pathway was proposed for the all-inorganic perovskite CsPbBr₃ NCs with potassium peroxydisulfate (K₂S₂O₈) as coreactant. In addition to the greenish ECL emission with its excellent stability, this study might open a door to further applications of perovskite-based ECL probes.

全无机钙钛矿CsPbBr ₃纳米晶体在水性介质中的阴极电化学发光性能

我们报告从水性介质中的所有无机钙钛矿纳米晶体（NCs）阴极电化学发光（ECL）。提出了以过氧二硫酸钾（K ₂ S ₂ O ₈）为共活化剂的全无机钙钛矿CsPbBr ₃ NCs的电子转移an灭途径。除了具有优异稳定性的绿色ECL发射外，这项研究还可能为钙钛矿型ECL探针的进一步应用打开一扇门。
