Abstract：

Accurate　lanthanides　featured　with　the　abundant　ladder-like　excited　states　may　enable　one　single　activator　to　exhibit　a　multitude　of　emission　bands.　The　elaborate　manipulation　on　such　emission　bands　can　realize　the　modulation　of　emission　color　and　therefore　lead　to　plenty　of　applications.　The　modification　of　up-conversion　dynamics　via　energy　migration　within　nanostructure　can　lead　to　temperature-dependent　colormetric　lanthanide　up-conversion　emissions　and　has　been　proposed　to　design　high-performance　luminescence　nanothermometers.　By　comparing　the　up-conversion　luminescence　thermal　behaviors　of　NaYbF4:Er3+　and　NaErF4　nanocrystals,　in　this　work,　we　demonstrate　that　a　delicate　design　for　the　energy　migration　path　within　nanocrystal　can　significantly　contribute　to　the　luminescence　thermometric　performance.　©　2025　Elsevier　Inc.
