Visible-blind ultra-violet (UV) photodetectors have great application prospects in military and civilian fields. Hence, it is important to develop high-efficiency UV photodetectors. Perovskite materials have been widely applied in many fields, such as solar cells, light-emitting diodes, and photodetectors, owing to their excellent optical properties. The CsPbCl₃ perovskite has a great potential in visible-blind UV photodetectors owing to its stable chemical properties and a suitable band gap. However, due to the extremely poor precursor solubility of CsPbCl₃, it is difficult to find a suitable solvent to prepare CsPbCl₃ films. In this study, we developed a two-step diffusion method to prepare CsPbCl₃ films. PbCl₂ and CsCl were dissolved in different solvents to overcome the solubility problem of CsPbCl₃. First, the PbCl₂ film was spin coated on a soda-lime glass. The CsCl solution was then continually dropwise spin-coated on the PbCl₂ film to form the CsPbCl₃ film. By controlling the morphology of PbCl₂ through different annealing temperatures, the influence of different PbCl₂ precursor films on microstructure of the CsPbCl₃ film was investigated. The X-ray diffraction and scanning electron microscopy profiles of the PbCl₂ precursor film and the CsPbCl₃ film suggested that when the annealing temperature was too low, excess dimethyl sulfoxide (DMSO) remained in the PbCl₂ precursor film, which hindered the transformation of CsPbCl₃. However, when the annealing temperature was too high, voids appeared in the CsPbCl₃ film due to excess DMSO volatilization, which caused pinholes in the CsPbCl₃ film. Finally, a pinhole-free, smooth CsPbCl₃ film with full grains was obtained when PbCl₂ was annealed at 80 ℃. To the best of our knowledge, this is the first time a high-quality CsPbCl₃ film with 1 μm grains was prepared using a two-step diffusion method. Photoelectrical characterizations, such as ultraviolet-visible absorption, steady-state photoluminescence (PL), and time-resolved PL characterizations, were studied to evaluate the quality of the film. The as-prepared CsPbCl₃ film had strong UV absorption and PL intensity, and its longer PL lifetime indicated that the film had fewer defect states. Furthermore, a UV photodetector with a lateral structure based on the CsPbCl₃ film was fabricated. The related electrical characterizations, such as current voltage curves, showed a good responsivity of 0.75 A·W^-1 and an outstanding detectivity of 7.8 × 10¹² Jones, which are better than those of contemporary commercial photodetectors. The findings of this study show that a two-step diffusion method can be used to prepare CsPbCl₃ films with better features and that it has a great potential in the development of UV photodetectors in the future.
