Controlling　the　laser　power　density　is　one　of　the　major　means　to　bring　photothermal　conversion　phenomenon.　However,　only　a　slight　temperature　enhancement　was　achieved　by　exposure　to　the　laser.　How　to　enhance　photothermal　conversion　to　develop　power-sensitive　fluorescence　intensity　ratio　technology　becomes　a　problem.　Here,　we　report　an　eco-friendly　niobate-based　ceramic　(K0.25Na0.25NbO3)　doped　with　rare　earth　ions　(Er3+,　Yb3+)　and　simultaneously　modified　with　CaCu3TiO4,　exhibiting　superior　photothermal　effect　(PTE)　and　fluorescence　intensity　ratio　(FIR).　Thereinto,　PTE　originating　from　the　up-conversion　luminescence　of　Er3+　greatly　elevates　due　to　the　Cu2+　quenching　and　Yb3+　sensitization.　Meanwhile,　the　defects　formed　by　the　volatilization　of　potassium　and　sodium　at　high　temperature　can　enhance　PTE　(70　°C,　0.4　W)　and　power　sensitivity　(Sp　=　0.61　W-1).　Under　multiple　power　cycles,　stable　FIR　of　the　ceramic　shows　outstanding　resistance　to　temperature　in　long-term　power-dependent　tests.　Furthermore,　this　strategy　can　open　opportunities　for　preparing　efficient　photothermal　conversion　ceramics　and　exploiting　PTE　for　vision-to-tactile　sensory　conversion.　©　2022　Elsevier　Ltd　and　Techna　Group　S.r.l.
