PbS/CdS core/shell quantum dots are applied as ultrasensitive, biocompatible, self‐calibrating, multi‐parametric temperature sensors by H. Zhao, A. Vomiero, and F. Rosei. On page 5741, they show how part of the colour emission comes from the PbS core and part from the CdS shell. The relative intensity of these emissions is temperature‐dependent, inducing color changes when the temperature varies. The lifetime and peak position of PbS emission also monotonically change with the temperature, offering a platform for a multi‐parametric detection system.
