Quench, Glow, or Stay Silent: Distance-Controlled Up-Conversion Emission near Metallic Nanowires

Maciej Cwierzona, Michal Zebrowski, Pavel Dziarhai +5

We demonstrate controlled transitions between competing radiative and nonradiative decay channels in the up-conversion luminescence of NaYF4:Er3+/Yb3+ nanocrystals placed in proxim…
