“…[21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39][40] Among various temperature-dependent fluorescence parameters, the temperature-based fluorescence intensity ratio (FIR) can circumvent the disturbances of the local environment and provide real-time feedback results. [41][42][43][44][45][46][47][48][49][50] In addition, Nd 3+ -based thermometers were proposed for bio-applications, and new multipurpose strategies, Cr 3+ -based Boltzmann thermometers, were demonstrated to be particularly promising. [51][52][53][54][55][56][57][58] Intense up-conversion luminescence and high-temperature sensitivity are vital parameters to construct an accurate thermometer, which can be optimized by selecting suitable rare earthdoped optical materials.…”
