Perovskite‐based photodetectors exhibit potential applications in communication, neuromorphic chips, and biomedical imaging due to their outstanding photoelectric properties and facile manufacturability. However, few of perovskite‐based photodetectors focus on ultraviolet‐visible‐short‐wavelength infrared (UV–Vis–SWIR) broadband photodetection because of the relatively large bandgap. Moreover, such...
Individual Perovskite Nanoplate Photodetectors
In article number 2301386, Lu Zhu, Shenghuang Lin, Haoran Mu, Zhanfeng Huang, and co‐workers design and fabricate an individual monocrystalline MAPbBr3 nanoplate‐based photodetector that simultaneously achieves efficient ultraviolet‐visible‐short‐wavelength infrared broadband photodetection and fast‐response. They find that perovskites with relatively...
While concerns about improving recharged afterglow intensity in vivo still motivate further exploration, afterglow nanoparticles (AGNP) offer unique optical merit for autofluorescence‐free biological imaging. Apart from efforts enhancing the afterglow emission properties of AGNP, improving afterglow excitation response to visible or near infrared light is important but has lacked success. Dye sensitization...
