对稀土掺杂上转换纳米材料的发光轮廓的精确控制对于其在广泛的研究领域中的应用至关重要。传统的化学方法可以导致颜色可调的发射，但它们通常需要对掺杂剂成分或掺杂浓度进行严格的修改。在本教程回顾中，我们重点介绍了许多补充方法，这些方法可在可见光谱范围内提供上转换发光的远程动态调制。本综述旨在总结用于控制具有固定材料成分的上转换纳米晶体的发射光谱的现有指南。该综述还将讨论操纵激发能的主要方法，并考虑纳米技术和生物科学之间的交叉领域进一步发展可能面临的研究挑战。
The precise control over the luminescence profile of lanthanide-doped upconversion nanomaterials is of fundamental importance for their applications in wide-ranging fields of research. Conventional chemical approaches can lead to color-tunable emissions, but they generally require stringent modification either on dopant composition or doping concentration. In this Tutorial Review, we highlight a number of complementary methods that offer remote dynamic modulation of upconversion luminescence across the visible spectrum. This review serves to provide a summary of existing guidelines for controlling the emission spectrum of upconversion nanocrystals with fixed materials composition. The review will also discuss the major approaches to manipulating excitation energies and consider likely research challenges for further development of the field at the interface between nanotechnology and biological science.
