Abstract

In recent years, fluorescent materials centered on the second near-infrared (NIR-II) window have emerged as a new research area of interest for prospective biomedical applications. Among the latest generation of NIR-II probes, rare earth nanocrystals (RE NCs) have distinguished themselves by their remarkable optical properties, such as high stability, large Stokes/anti-Stokes shift, a broad excitation spectral bandwidth, and a prolonged fluorescence lifetime. Particularly, via ingenious design and meticulous manipulation of the structure and composition, the energy transfer and photon transition during the luminescence process can be precisely regulated, thereby achieving substantial optimization of optical performance. In this review, we will briefly outline the NIR-II emission mechanism of RE NCs and focus on the luminescence enhancement strategies of the latest advancements, with the intention of furnishing valuable references for research in related fields.

具有增强NIR-II发光的稀土纳米晶体

近年来，以第二近红外（NIR-II）窗口为中心的荧光材料已成为生物医学应用前景的一个新的研究领域。在最新一代NIR-II探针中，稀土纳米晶体（RE NCs）以其高稳定性、大Stokes/反Stokes位移、宽激发光谱带宽和长荧光寿命等显著的光学特性而备受关注。特别是，通过巧妙的设计和对结构和组成的细致操作，可以精确调节发光过程中的能量传递和光子跃迁，从而实现光学性能的实质性优化。本文将简要介绍稀土纳米材料的NIR-II发光机理，重点介绍其发光增强策略的最新进展，以期为相关领域的研究提供有价值的参考。
