Abstract：

Currently,　advanced　optical　security　techniques　are　imminent　in　response　to　the　increasingly　rampant　counterfeit　and　pirated　goods　on　a　global　scale.　Herein,　hexagonal　Na(NdxY1−x)F4　(x　=　0–1)　solid-solution　nanocrystals　(NCs)　embedded　glasses　are　successfully　fabricated　via　in　situ　glass　crystallization.　Benefited　from　the　protection　of　inorganic　glass,　Na(NdxY1−x)F4　NCs　exhibit　superior　long-term　stability　and　can　endure　high-power　808 nm　laser　irradiation.　Importantly,　opposite　variations　between　near-infrared　(NIR)　luminescence　and　laser-induced　temperature　can　be　detected　for　the　nanocomposites,　which　are　sensitive　to　Nd3+　doping　concentration.　As　a　proof-of-concept　experiment,　Nd3+　concentration　dependent　anti-counterfeiting　patterns　with　high-concealment　and　high-precision　are　designed　and　show　bright　emission　and　dimmish　thermal　images　in　Nd3+-tenuous　composites　under　the　irradiation　of　808 nm　laser,　while　opposite　displays　can　be　achieved　in　Nd3+-enriched　one.　This　kind　of　information　encryption　triggered　by　a　commercial　single　light　source　to　achieve　dual　opposing　displays　in　one　material　can　effectively　improve　security　in　anti-counterfeiting.　©　2022　Wiley-VCH　GmbH.
