Abstract：

Near-infrared　(NIR)　photostimulated　luminescence　(PSL)　nanocrystals　(NCs)　exhibit　deep　penetrability　and　low　autofluorescence,　recently　evoking　extensive　interest　for　their　application　in　biosensing.　Nevertheless,　most　of　the　NIR　PSL　NCs　encounter　substantial　constraints　in　biomedicine　applications,　primarily　stemming　from　the　necessity　of　high-power　diode　laser　stimulation　or　their　larger　particle　size.　Herein,　we　design　a　new　class　of　NIR　light-emitting　diode　(LED)　PSL　NCs　based　on　SrS:Eu2+　NCs,　which　were　coated　with　SrS　shell　to　improve　their　stability　and　photoluminescence　(PL)　intensity.　The　trap　depth　and　density　of　the　NCs　were　further　tailored　through　thermal　annealing　and　Dy3+　co-doping,　resulting　in　efficient　NIR　PSL　with　a　duration　time　longer　than　2　h　by　stimulation　with　an　NIR　LED　in　a　broad　region　within　700–1400　nm.　Benefiting　from　their　excellent　NIR　PSL,　we　showcased　the　potential　of　SrS:Eu2+,Dy3+@SrS　NCs　as　sensitive　nanoprobes　for　tumor-targeted　imaging　in　zebrafish　with　a　signal-to-noise　ratio　of　18.9.　These　findings　demonstrate　the　significant　promise　of　the　proposed　SrS:Eu2+,Dy3+@SrS　nanoprobes　for　in　vivo　bioimaging,　which　may　pave　the　way　for　the　development　of　effective　NIR　PSL　nanoprobes　for　diverse　bioapplications　in　the　future.　©　2024　Elsevier　B.V.
