All-inorganic　perovskite　quantum　dots　(PQDs)　have　excellent　photoelectric　performance,　such　as　high　photoluminescence　quantum　yield　(PLQY),　narrow　full　width　at　half-maximum　(FWHM),　and　emission　spectra　covering　the　visible　light　wavelength.　The　emission　color　can　be　tuned　over　the　full　visible　spectral　region　making　them　promising　for　white-light-emitting　diodes　(WLEDs).　Further　control　over　the　optical　and　magnetic　properties　of　PQDs　can　be　achieved　through　doping　of　transition　metal　ions　such　as　Mn2+　ions.　In　this　paper,　a　rapid　doping　method　is　employed　at　room　temperature　by　using　strong-acid　cation-exchange　resin　during　the　metal　ions　doping　process,　which　shortens　the　doping　time,　and　Mn:CsPb(Cl/Br)3　QDs　were　obtained.　By　controlling　the　reaction　time　between　strong-acid　cation-exchange　resin　and　PQDs,　we　achieve　different　levels　of　manganese　doping,　resulting　in　a　new,　to　the　best　of　our　knowledge,　fluorescence　peak　at　600　nm.　The　introduction　of　strong-acid　cation-exchange　resin　preserves　the　integrity　of　the　PQD　structure,　while　completing　the　doping　within　30　min.　Due　to　the　low　cost　and　mild　reaction　conditions　of　resin,　it　is　expected　that　the　Mn:CsPb(Cl/Br)3　QDs　can　be　mass-produced　in　large　quantities.　In　addition,　in　order　to　provide　high-quality　white　light　emission,　and　prevent　anion　exchange　reactions　when　mixed　with　CsPbBr3　QDs,　the　CsPbBr3　QDs　are　coated　with　silicon.　Finally,　by　combining　ultraviolet-lightemitting　diodes　(UVLEDs)　with　the　aforementioned　PQD　mixture,　this　paper　successfully　fabricates　WLEDs　and　demonstrates　its　excellent　photoelectric　performance.　The　constructed　WLEDs　produce　warm　white　light　with　a　high　color　rendering　index　(CRI)　of　91　and　a　high　correlated　color　temperature　(CCT)　of　5966　K,　and　the　luminous　efficacy　(LE)　of　WLEDs　is　41　lmW-1.　(c)　2024　Optica　Publishing　Group
