摘要：
The absorption/emission spectra of excited states (singlets and triplets) and ions generated by pulse radiolysis method in the pyrene-Nafion system were investigated. Scavenging of positive charges by pyrene was only observed. Pyrene fluorescence (monomer and excimer) was found to be produced mainly as a result of Cerenkov photoexcitation. In addition, pyrene triplets can be generated by ionic recombination in mu s times. The influence of matrix properties on pyrene ions yield was discussed. (C) 1999 Elsevier Science Ltd.
