摘　　要： 用皮秒锁模Ｎｄ：ＹＡＧ激光器的倍频输出（５３２ｎｍ）作为激发光，用同步扫描条纹相机系统对聚对苯乙炔ＰＰＶ的两种衍生物，Ｐｏｌｙ（２－ｍｅｔｈｏｘｙ－５－（４－ｂｕｔｅｎｙｌｏｘｙ）ｐｈｅｎｙｌｅｎｅｖｉｎｙｌｅｎｅ）（ＭＢ－ＰＰＶ）和Ｐｏｌｙ（２－ｍｅｔｈｏｘｙ－５－（４－ｂｒｏｍｏ－ｂｕｔｏｘｙ）ｐｈｅｎｙｌｅｎｅｖｉｎｙｌｅｎｅ）（ＭＢＢ－ＰＰＶ），与富勒烯Ｃ６０的组合薄膜进行时间分辨荧光测量。 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)/C60 and Poly(2methoxy5(4bromobutoxy) phenylene vinylene)(MBBPPV)/C60.Comparing with the pure MBBPPV film,PL weakening and quenching of MBBPPV were observed in the multilayer and mixed MBBPPV/C60 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 C60 molecule,Further measurements indicate that there is no noticeable dependence of the ET process on the temperature in the combination films.
