  • Abstract
    We report a novel method that utilizing polyethylene polyamine (PEI)/quantum dots (QDs) composite film for the detection of H2O2 vapor via a fluorescence turn-on mode. It could be easily dispersed and quite stable under light irradiation. And compared with QDs-only film, the composite film is immune to the interference signal from other volatile organic vapors thanks to that only the oxidation-reduction reaction can terminate the electron transfer process between PEI and QDs.
