Abstract：

Perovskite　quantum　dots　(PQDs)　are　getting　more　and　more　attention　for　their　unique　optical　properties　such　as　high　photoluminescence　quantum　yield,　narrow　emission　spectrum,　and　adjustable　emission　wavelength.　However,　PQDs,　especially,　CH　3　NH　3　PbX　3　PQDs　have　very　poor　stability　due　to　their　easy　decomposition　by　water　and　oxygen　in　the　air.　Herein,　we　grew　nano-sized　CH　3　NH　3　PbBr　3　PQDs　in　situ　within　a　kind　of　micro-sized　metal-organic　frameworks　(Bio-MOF-1)　to　obtain　MOFs-protected　PQD　composites　(PQDs-Bio-MOF-1).　The　MOF　protection　only　enables　the　PQD　composites　to　maintain　the　fluorescence　characteristics　of　PQDs,　but　also　obviously　improves　the　stability　of　PQDs　in　the　air,　showing　promising　application　in　light-emitting　diodes　(LEDs).　©　2019　Elsevier　Inc.
