Abstract
at 293 K, and temperature uncertainties below 0.7 K within the physiological range 293-233 K, operating entirely in the first and second biological windows. These sensitivity and temperature uncertainty values were achieved by defining two thermometric parameters as the luminescence intensity ratios, exploiting a combination of emissions from both ion species.
