Abstract

Although significant progress has been made in the development of all-inorganic CsPbI3 (X = Br, Cl and I) perovskites, some crucial points typically concerning their stability and toxicity due to the presence of Pb are yet to be addressed. In the present study, we report the growth of qualified all-inorganic CsPbI3 perovskite nanobelts with high yield and purity via a solvothermal route; herein, Sn has been incorporated to substitute Pb to reduce the toxicity of these nanobelts. XPS analyses showed that the Sn-doped CsPbI3 nanobelts were substantially stabilized and exhibited satisfied stability for up to 15 days when maintained under air conditions. The as-constructed photodetectors (PDs) based on a single CsPb0.922Sn0.078I3 nanobelt displayed overall excellent performance with an ultrahigh detectivity of up to 6.43 × 1013 Jones, which was comparable to the best values of all-inorganic perovskite PDs reported to date.
