Overview

Doping perovskites enhances NIR photoresponse while maintaining X-ray detection performance, suggesting a new photodetection strategy.

Key Points

  • This research aims to expand the detection range of perovskite photodetectors into the near-infrared region by doping techniques.
  • Introduced Fe dopants into Cs2AgBiBr6 perovskites.
  • Evaluated photoresponse and spectral range up to 1200 nm.
  • Assessed intrinsic X-ray detection performance alongside NIR enhancement.
  • Achieved extended spectral response to ∼1200 nm in the NIR region.
  • Fe doping did not affect X-ray detection capabilities.
  • Significant enhancement in NIR photoresponse observed.
