In article number 2002266, John A. Capobianco and co‐workers present the novel multiemission particle velocimetry technique, which exploits the upconversion luminescence dynamics in core–shell nanoparticles engineered with different emitting ions. Their sequential emissions are characterized by a known time interval, resulting in the possibility of accurately measuring the velocity of the nanoprobes flowing through a microcapillary without the need for any calibration.
