A　flexible　hybrid　white　light　emitting　diode　(LED),　in　which　the　CdSe/ZnS　quantum　dots　(QDs)　acted　as　an　orange　emitter　and　small　organic　molecules　as　the　blue　emitter　in　a　multilayered　structure　was　fabricated　by　spin-coating.　The　poly　(N-vinylcarbazole)　(PVK)　was　added　in　the　emitting　layer　to　adjust　QDs　distribution　in　polymer　matrix.　By　increasing　the　concentration　of　PVK,　the　electroluminescent　intensity　at　610　nm　emission　was　enhanced　since　QDs　had　a　better　dispersibility　in　polymer　matrix　with　the　presence　of　PVK,　and　a　pure　white　light　emission　was　obtained　due　to　the　optimized　architecture　of　the　hybrid　active　layer.　Our　study　provides　a　novel　method　for　improving　the　device　performance　of　hybrid　white　LEDs　by　controlling　the　QDs　distribution　in　the　active　layer.　(C)　2014　Elsevier　Ltd.　All　rights　reserved.
