镧系元素掺杂的高效率上转换纳米粒子的合成
Synthesis of Highly Efficient Lanthanide Upconversion Nanoparticles
摘要
上转换纳米粒子在近红外光激发下发射紫外/可见/近红外光, 也称为反斯托克斯发射。这一独特的光学性质排除了来自于生物材料的背景荧光和散射光, 为光学生物应用, 如生物成像、光动力学治疗、药物输送等开辟了新的途径。为了实现更好的应用性能, 在许多情况下需要高效率的镧系元素上转换纳米颗粒。一般来说, 上转换纳米粒子的质量往往与其合成方法有关。在这篇综述中, 我们将主要阐述上转换纳米粒子的各种合成过程, 总结了几种获得高发光效率的上转换纳米粒子的有效途径。
Abstract
Upconversion nanoparticles can emit ultraviolet/visible/near-infrared light under near-infrared excitation, also known as anti-Stokes emission. This unique optical property precludes background fluorescence and light scattering from biological materials, which opens up new avenues for optical bio-applications, such as bioimaging, photodynamic treatment, drug delivery, etc. In order to achieve better application performance, highly efficient lanthanide upconversion nanoparticles is desired in many cases. Generally, the quality of the upconversion nanoparticles is always related to their synthetic methods. In this review, we will focus primarily on the various synthetic procedures for the upconversion nanoparticles. Moreover, several effective ways to obtain high luminescence efficiency are summarized.
