摘要：

By using picosecond laser beam with high repetition rate, we have studied the irradiation effect of the photoluminescence spectrum of PVK/C-60 composite films which were fabricated by physical jet deposition technique. With long time irradiation of 532 nm beam, the intensity of PL emission at 630 nm of PVK molecule would increase steadily in the mixed him reflecting that the population of the triplet state of C-60 molecule has a great effect on the excitation transfer process in the composite films.
