摘要

Cesium lead halide perovskites (CsPbX3) have become superior candidates for prospective optoelectronic applications. However, the currently reported CsPbX3 quantum dots entail complex production processes and high environmental requirements. In this work, all-inorganic perovskite CsPbBr3 films were prepared by a facile printing strategy, and corresponding photoelectric detection devices were designed and their optical response characteristics investigated. The results showed that the pure CsPbBr3 film is relatively smooth and can maintain high stability under an ambient environment. Furthermore, the thin film prepared by the printing strategy has the advantages of convenience, uniformity, and high photoluminescence, with good application prospects in the field of CsPbBr3 quantum dots.
