Abstract

Herein, we describe simple, fast and reproducible halide ion exchange reactions in CsPbX₃ (X = Cl, Br, I) nanocrystals (NCs) at room temperature. Through the simple adjustment of the halide ion concentration, the photoluminescence of these NCs can be tuned over the entire visible region (425-655 nm). Photodetector devices based on entirely inorganic CsPbI₃ NCs are demonstrated for the first time. The photodetectors exhibited a good on/off photocurrent ratio of 10⁵.
