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.

银孔帽纳米阵列在近红外-II 窗口显著增强掺杂 Ce3+ 的镧系下转换纳米粒子的等离子体发光（先进光学材料 30/2024）

谢芳及其合作者的研究（见文章编号 240660）通过将 Ce3+ 离子整合到 NaYF4:Yb3+,Er3+ 纳米粒子中，并使用银孔帽纳米阵列（Ag-HCNAs），在近红外-II 窗口显著增强了镧系元素下转换纳米粒子的发光能力。通过优化掺杂和等离子效应，这种组合策略实现了两个数量级以上的增强。三维 FDTD 模拟和时间分辨测量结果表明，电场显著增强，辐射衰减率提高，为近红外-II 区的生物传感和生物成像应用带来了可喜的进步。
