Lanthanide-doped bismuth-based nanophosphors for ratiometric upconversion optical thermometry

“…9 Moreover, this method is more stable than other non-contact detection methods because lots of nontemperature factors are difficult to interfere with it during the temperature detection. 1,2,10 In spite of the early achievement, it is signicant to the eld of nanothermometry to undergo evolution to provide methods with desirable sensitivity, dynamic range, and superior photostability. 1,2,11 To date, a multitude of optical temperature sensing technologies has been explored on the basis of lanthanide-doped nanocrystals (Ln-NCs), the spectral diversity of which provides more options for the application of nanothermometry.…”
