Abstract

Lanthanide-sensitized upconverting nanoparticles (UCNPs) are widely studied because of their unusual optical characteristics, such as large antenna-generated anti-Stokes shifts, high photostability, and narrow emission bandwidths, which can be harnessed for a variety of applications including bioimaging, sensing, information security and high-level anticounterfeiting. The diverse requirements of these applications typically require precise control over upconversion luminescence (UCL). Recently, the concept of energy migration upconversion has emerged as an effective approach to modulate UCL for various lanthanide ions. Moreover, it provides valuable insights into the fundamental comprehension of energy transfer mechanisms on the nanoscale, thereby contributing to the design of efficient lanthanide-sensitized UCNPs and their practical applications. Here we present a comprehensive overview of the latest developments in energy migration upconversion in lanthanide-sensitized nanoparticles for photon upconversion tuning, encompassing design strategies, mechanistic investigations and applications. Additionally, some future prospects in the field of energy migration upconversion are also discussed.

通过镧系元素敏化纳米粒子中的能量迁移实现光子上转换调谐

镧系元素敏化上转换纳米粒子（UCNPs）由于其不同寻常的光学特性而被广泛研究，例如大天线产生的抗斯托克斯位移，高光稳定性和窄发射带宽，可以用于各种应用，包括生物成像，传感，信息安全和高级防伪。这些应用的不同要求通常需要对上转换发光（UCL）进行精确控制。最近，能量迁移上转换的概念已经成为一种有效的方法来调节各种镧系离子的UCL。此外，它还为纳米尺度上能量传递机制的基本理解提供了有价值的见解，从而有助于设计高效的镧系敏化UCNPs及其实际应用。在这里，我们全面概述了用于光子上转换调谐的镧系敏化纳米粒子的能量迁移上转换的最新进展，包括设计策略，机理研究和应用。最后，对能量迁移上转换领域的发展前景进行了展望。
