摘　　要：Luminescent materials capable of photoswitching driven by optical stimulation have been the robust tools of diverse advanced technologies,including superresolution imaging,nanophotonics,data storage,and optogenetics[1].Up to date,various kinds of photoswitchable materials have been developed,most of which(e.g.,organic fluorophores and proteins)are prone to photodegradation and usually operate in the ultraviolet or visible spectral regions[2].Near-infrared(NIR)light excitable inorganic upconversion nanocrystals(NCs)can offer significantly improved photostability and penetration depth.
