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.

多发射粒子测速：上转换纳米系统的内在生命周期动力学在多发射粒子测速中的关键作用（Adv。Mater。42/2020）

在编号2002266中，John A. Capobianco及其同事提出了一种新颖的多发射粒子测速技术，该技术利用了采用不同发射离子设计的核壳纳米粒子的上转换发光动力学。它们的连续发射以已知的时间间隔为特征，从而有可能在无需任何校准的情况下准确测量流过微毛细管的纳米探针的速度。
