| 英文摘要 | Photoluminescence (PL) and time-resolved spectroscopic studies on plasmonically coupled semiconductor nanoparticles ( SNPs) have demonstrated the PL quenched and lifetime enhanced of SNPs in the presence of metal nanoparticles (MNPs). The hybrid colloidal CsPbBr3 perovskite SNPs/Pt MNPs (S-M) structures exhibit novel optical properties due to the synergetic interaction between the individual components. In hybrid S-M nanostructures colloidal chemistry incorporates SNP and MNPinto a single unit resulting in the formation of plexciton (or excimon) which has now been established in a series of hybrid structures. The experimental results of femtosecond transient absorption (TA) spectroscopy based on the time-resolved pump-probe confirm the transformation from excitons to plexcitons. It was found that the experimental data can't be well described by the theory based on conventional Foster resonance energy transfer (FRET). The differences between theory and experiment may be due to the missing some PbBr2 PL peaks, the reason will be revealed further. |
