Field-induced ionic motions in all-inorganic CsPbBr 3 perovskite quantum dots (QDs) strongly dictate not only their electro-optical characteristics but also the ultimate optoelectronic device performance. Here, we show that the functionality of a single Ag/CsPbBr 3 /ITO device can be actively switch...
