摘　　要：稀土掺杂上转换发光材料的荧光强度通常会随着温度上升而呈现明显的热猝灭现象,这对其在温度传感、防伪、显示等方面的应用产生了极大的障碍。最近,研究人员在实验中发现了上转换发光强度随温度升高而增强的特殊现象,并开展了大量工作揭示其内在机理以及可能影响热增强效应的因素。上转换热增强效应的机理探究和优化对于未来开发新型的稀土上转换发光材料提供了新颖的思路,也为稀土上转换发光材料的应用研究奠定了基础。本文对荧光热增强型稀土掺杂上转换发光材料的最新研究进展进行了简单总结和梳理,主要介绍了荧光热增强效应的内在机理以及潜在应用,并展望了未来研究中所面临的机遇和挑战。Rare-earth doped upconversion materials generally feature serious thermal quenching as the temperature rising,which greatly limits their applications in optical thermometry,anti-counterfeiting,and display.Recently,unique thermal enhancement phenomenon of upconversion intensity has been detected by many groups,and great efforts have been devoted to revealing the mechanism and the influential factors.Meanwhile,the theoretical exploration and optimization of thermal enhancement effect open a novel and effective avenue for the rational design and applications of rare-earth doped upconversion materials.In this review,the recent advances in thermos-enhanced rare-earth ions doped upconversion materials are elaborately summarized from inner mechanism to possible applications,with the perspective and outlook in the emerging challenges in the future research.
