| Abstract: | We report the integrated and picosecond time-resolved photoluminescence (TRPL) measurement from two kinds of combination films: Poly(2-methoxy-5-(4-butenyloxy)phenylene vinylene) (MB-PPV)/C60 and Poly (2-methoxy-5-(4'-bromo-butoxy) phenylene vinylene) (MBB-PPV)/C60. Comparing with the pure MBB-PPV film, PL weakening and quenching of MBB-PPV were observed in the multilayer and mixed MBB-PPV/C60 films respectively. From TRPL spectra, the change of PL decay lifetime could be clearly seen, those could be attributed to the excitation transfer (ET) process between the excited MBB-PPV molecule and C60 molecule. Further measurements indicate that there is no noticeable dependence of the ET process on the temperature in the combination films. |
