Fig. 1. Pixel-level X-ray to infrared image fusion and work mechanism.
a Traditional pixel-level X-ray to infrared image fusion by using three photodetectors at corresponding wavebands and vision algorithm. b Pixel-level X-ray to infrared image fusion by using one single flexible and broadband photodetector. c Working principle of broadband PbS CQDs photodetector from X-ray to infrared. d Non-equilibrium carriers generation of PbS CQDs excited by X-ray and ultraviolet-visible-infrared irradiation. e Schematic diagram of PbS CQDs film under bending state.
