掺镧上转换纳米粒子(UCNPs)具有将近红外光转换为较短波长辐射的独特发光特性，近年来成为一个新兴的研究领域。UCNPs在发光标记、显示器、生物成像、生物分析、药物输送、传感器和防伪应用方面具有良好的前景。随着这一领域的大量研究和快速发展，UCNPs具有传统有机染料和量子点无法比拟的独特优势，有望成为一类新型的发光探针。其中，聚合物在基质材料、水溶性、连接活性靶向分子、生物相容性、刺激响应行为等方面发挥着重要的作用。本文简要介绍了上转换纳米晶的组成、光学机理、结构，重点介绍了各种功能纳米碳管/聚合物纳米杂化材料的研究工作以及在应用方面的许多新成果。
Lanthanide-doped upconversion nanoparticles (UCNPs) have been an emerging and exciting research field in recent years due to their unique luminescent properties of converting near-infrared light to shorter wavelength radiation. UCNPs offer excellent prospects in luminescent labeling, displays, bioimaging, bioassays, drug delivery, sensors, and anticounterfeiting applications. Along with the abundant studies and rapid progress in this area, UCNPs are promising to be a new class of luminescent probe owing to their special advantages over the conventional organic dyes and quantum dots. Among them, polymers play an important role to improve properties or endow new function of UCNPs such as for matrix materials, water solubility, linking active targeting molecules, biocompatibility, and stimuli-responsive behavior. This article briefly reviews the compositions, optical mechanisms, architectures of upconversion nanocrystals and highlights the works on various functional UCNPs/polymer nanohybrids as well as many new interesting fruits in applications.
