Figure 3. Dimensionality reduction in luminescence nanothermometry.

Caption

(a) The application of a dimensionality reduction approach (in this case a linear transformation such as Principal Component Analysis) results in the definition of a new space of coordinates wherein a temperature change is more easily quantifiable. (b) An example of the increased precision of luminescence nanothermometry achieved applying dimensionality reduction (DR) approaches (teal line) compared to a classical trial-and-error approach (magenta line) to define the thermometric parameter. The black line is the real temperature of the medium in which the luminescent nanothermometers are embedded.
