摘要

能源密集型技术和高精度研究需要节能技术和材料。基于透镜的光学显微镜技术可用于生命科学和其他技术领域的低能耗应用,但由于光衍射的原因,标准技术无法实现纳米级应用。远场超分辨率技术突破了光衍射的限制,实现了分子尺度的三维应用,并努力减少能源消耗。通常,有针对性的超分辨率技术可实现高分辨率,但要超越纳米材料中的竞争光学转换,所需的高光强可能会导致光损伤和高能耗。为了提高这些技术的分辨率和效率,实现低能耗超分辨率应用,人们在纳米材料的开发方面做出了巨大努力。掺杂镧系离子的上转换纳米粒子表现出多个长寿命激发能态并发出上转换发光,这使得需要低强度光的定向超分辨率技术得以发展。在这些技术中使用掺杂镧系离子的上转换纳米粒子,用于新兴的低能超分辨率应用,将对生命科学和其他技术领域产生重大影响。在这篇综述中,我们介绍了掺杂镧系离子的上转换纳米粒子在低强度光下的超分辨率动力学及其在定向超分辨率技术中的应用。我们重点介绍了掺杂镧系离子的上转换纳米粒子的低能超分辨应用,以及相关的研究方向和挑战。我们的目的是分析使用掺杂镧系离子的上转换纳米粒子的定向超分辨技术,强调镧系离子在低强度光下超越衍射极限的基本跃迁机制,并探讨其对低能纳米尺度应用的影响。

Lanthanide ion-doped upconversion nanoparticles for low-energy super-resolution applications

Lanthanide ion-doped upconversion nanoparticles for low-energy super-resolution applications

Energy-intensive technologies and high-precision research require energy-efficient techniques and materials. Lens-based optical microscopy technology is useful for low-energy applications in the life sciences and other fields of technology, but standard techniques cannot achieve applications at the nanoscale because of light diffraction. Far-field super-resolution techniques have broken beyond the light diffraction limit, enabling 3D applications down to the molecular scale and striving to reduce energy use. Typically targeted super-resolution techniques have achieved high resolution, but the high light intensity needed to outperform competing optical transitions in nanomaterials may result in photo-damage and high energy consumption. Great efforts have been made in the development of nanomaterials to improve the resolution and efficiency of these techniques toward low-energy super-resolution applications. Lanthanide ion-doped upconversion nanoparticles that exhibit multiple long-lived excited energy states and emit upconversion luminescence have enabled the development of targeted super-resolution techniques that need low-intensity light. The use of lanthanide ion-doped upconversion nanoparticles in these techniques for emerging low-energy super-resolution applications will have a significant impact on life sciences and other areas of technology. In this review, we describe the dynamics of lanthanide ion-doped upconversion nanoparticles for super-resolution under low-intensity light and their use in targeted super-resolution techniques. We highlight low-energy super-resolution applications of lanthanide ion-doped upconversion nanoparticles, as well as the related research directions and challenges. Our aim is to analyze targeted super-resolution techniques using lanthanide ion-doped upconversion nanoparticles, emphasizing fundamental mechanisms governing transitions in lanthanide ions to surpass the diffraction limit with low-intensity light, and exploring their implications for low-energy nanoscale applications.
