| Abstract: | The results of interaction between CdSe quantum dots and polyaniline were reported. Polyaniline effectively decreases the emission of CdSe quantum dots, and the CdSe luminescence lifetime is decreased by the addition of polyaniline. The mechanism of the emission observed in CdSe is assumed to result from the energy transfer and from the combination of surface-trapped electrons and holes energy is transferred from CdSe to polyaniline, and polyaniline occupies the hole sites. |
