title: Visible blind ultraviolet photodetector based on CH3NH3PbCl3thin film.
abstract: We report a prototypical device of CH3NH3PbCl3film ultraviolet photodetectors that were fabricated with a coplanar metal-semiconductor-metal Au interdigital electrode configuration. Pure phase CH3NH3PbCl3films with a good crystallinity were formed by a hybrid sequential deposition process featured with inter-diffusion of PbCl2and CH3NH3Cl upon annealing. The CH3NH3PbCl3film photodetector exhibits a high responsivity of 7.56 A /W at 360 nm, a ultraviolet/visible rejection ratio (R360 nm/R500 nm) was about two orders of magnitude and fast response speed with a rising time of 170 μs and a decay time of 220 μs. All the above results demonstrate CH3NH3PbCl3film photodetector as a competitive candidate in the application of visible blind UV detectors.
