Fig. 4

a Schematic illustration of X-ray, visible and infrared imaging process. The images were obtained by the same PbS CQDs photodiode array. b Photograph of a capsule inside and outside captured by a smartphone silicon imager. Soft plastic filled with black ink wrapping an iron wire is placed inside the capsule. Images of the capsule obtained by the photodiode array under X-ray (c), visible (450 nm, d) and NIR (970 nm, e) illumination. To guide the eye, black dotted lines show the outlines of capsule, soft plastic and iron wire. f Date process for pixel-level image fusion. g Fused image of X-ray, visible and NIR images.
