Boltzmann- and Non-Boltzmann-Based Thermometers in the First, Second and Third Biological Windows for the SrF2:Yb3+, Ho3+ Nanocrystals Under 980, 940 and 915 nm Excitations – Nanoscale Research Letters

Structure Characterization Figure 1a–e shows the TEM images of SrF2:Yb3+/Ho3+(12/x mol%) doped with different Ho3+ concentrations. The morphology of these NCs exhibits an ellipse or rectangle shape. Figure 1f demonstrates the average…
