摘　　要：稀土掺杂的上转换发光纳米材料在信息安全、生物医学、光纤通信、显示和能源等众多领域有着巨大的应用潜力,受到了相关各领域研究人员的广泛关注。特别是近年来发展起来的具有正交激发发射特性的上转换发光纳米颗粒,其可在不同的激发条件下产生动态变化的光色输出,因而具备一系列新的特性与功能,大大地扩展了应用范围。本文综述稀土离子正交上转换发光的发展历程,系统论述了基于核壳结构的正交激发发射体系的设计原理和构建方法,介绍了其在信息存储、安全防伪、显示、传感、生物成像及治疗等领域的最新研究进展,并探讨了未来相关研究中可能面临的机遇和挑战。Rare earth-doped upconversion luminescence nanomaterials have received considerable attention from researchers due to their great potential for applications in many fields such as information security,biomedicine,optical fiber communication,digital displays,and energy.The recently-developed upconversion luminescence nanoparticles with orthogonal excitation-emission properties have attracted especially strong research interest because their distinct luminescence outputs can be dynamically modulated by switching the excitation conditions.The orthogonal luminescence properties further endow such nanocrystals with a set of new features and functionalities,which largely expands their potential applications.This review summarizes the progress in the development of orthogonal upconversion luminescence of rare earth ions,and provides a systematic discussion on design principles and construction strategies of orthogonal excitation-emission systems based on core-shell structures,as well as introduces their recent advances in various fields of applications including data storage,security anti-counterfeiting,digital displays,sensing,bioimaging and therapy.Furthermore,the prospective opportunities and challenges in the future research of orthogonal luminescence systems are also provided.
