Abstract：

Lanthanide　(Ln3+)-doped　upconversion　(UC)　nanoprobes,　which　have　drawn　extensive　attention　for　various　bioapplications,　usually　suffer　from　small　absorption　cross-sections　and　weak　luminescence　intensity　of　Ln3+　ions.　Herein,　we　report　the　controlled　synthesis　of　a　new　class　of　Ln3+-doped　UC　nanoprobes　based　on　CsLu2F7:Yb/Er　nanocrystals　(NCs),　which　can　effectively　increase　the　intersystem　crossing　(ISC)　efficiency　from　singlet　excited　state　to　triplet　excited　state　of　IR808　up　to　99.3　%　through　the　heavy　atom　effect.　By　virtue　of　the　efficient　triplet　sensitization　of　IR808,　the　optimal　UC　luminescence　(UCL)　intensity　of　IR808-modified　CsLu2F7:Yb/Er　NCs　is　enhanced　by　1309　times　upon　excitation　at　808　nm.　Benefiting　from　the　intense　dye-triplet-sensitized　UCL,　the　nanoprobes　are　demonstrated　for　sensitive　assay　of　extracellular　and　intracellular　hypochlorite　with　an　808-nm/980-nm　dual　excited　ratiometric　strategy.　©　2021　Wiley-VCH　GmbH
