| 英文摘要 | Doped nanoparticles were prepared from pyrene and phenanthrene using a facile reprecipitation method. the doped nanoparticles presented unique delayed fluorescent emissions of pyrene under the unprotected condition. the ratio of the intensity of delayed fluorescence (i(df)) to that of phosphorescence (i(p)) is about 4: 1, which almost keeps unchanged with the decrease of pyrene content at room temperature. the intensity of the delayed fluorescence emissions is dependent on the relative content of pyrene, as well as the aggregation degree of nanoparticles. the delayed emissions are contributed to efficient triplet-triplet energy transfer from phenanthrene (donor) to pyrene (acceptor). steady fluorescence measurement have proved that the singlet-singlet energy transfer process was also existent dominated by the radiation energy transfer mechanism. |
