Core–shell quantum dots serve as self‐calibrating, ultrasensitive, multiparametric, near‐infrared, and biocompatible temperature sensors. They allow temperature measurement with nanometer accuracy in the range 150–373 K, the broadest ever recorded for a nanothermometer, with sensitivities among the highest ever reported, which makes them essentially unique in the panorama of biocompatible nanothermometers with potential for in vivo biological thermal imaging and/or thermoablative therapy.
