In article 1701635, by Ute Resch‐Genger, Artur Bednarkiewicz, and co‐workers, Yb3+ and Ho3+ co‐doped core–shell colloidal nanoparticles are synthesized and studied. The obtained nanocrystals were designed to have the same chemical composition, but diverse spatial distribution of dopants. The observed differences shine new light on the photo‐physical behavior of luminescent nanoparticles with tailored...
At the core of luminescence color and lifetime tuning of rare earth doped upconverting nanoparticles (UCNPs), is the understanding of the impact of the particle architecture for commonly used sensitizer (S) and activator (A) ions. In this respect, a series of core@shell NaYF4 UCNPs doped with Yb3+ and Ho3+ ions are presented here, where the same dopant concentrations are distributed in different particle...
