Abstract：

Polyamine-functionalized　carbon　quantum　dots　(CQDs)　with　high　fluorescence　quantum　yield　(42.5%)　have　been　synthesized　by　the　low　temperature　(＜200　°C)　carbonization　of　citric　acid　with　branched　polyethylenimine　(BPEI)　in　one　simple　step.　The　obtained　BPEI-CQDs　are　spherical　graphite　nanocrystals　(average　6.2　nm　in　size)　capped　with　abundant　BPEI　at　their　surfaces.　It　is　the　first　report　that　CQDs　are　both　amino-functionalized　and　highly　fluorescent,　which　suggests　their　promising　applications　in　chemical　sensing.　©　2012　Elsevier　Ltd.　All　rights　reserved.
