Abstract

Enhanced Luminescence of Lanthanide Downconversion Nanoparticles The study by Fang Xie and co-workers (see article number 240660) demonstrates remarkable downconversion luminescence enhancement in the NIR-II window by integrating Ce3+ ions into NaYF4:Yb3+,Er3+ nanoparticles and using silver hole-cap nanoarrays (Ag-HCNAs). This combined strategy achieves over two orders of magnitude enhancement through optimized doping and plasmonic effects. Insights from 3D FDTD simulations and time-resolved measurements reveal significant electric field enhancements and increased radiative decay rates, offering promising advancements for biosensing and bioimaging applications in the NIR-II region.
