摘要：

Transient absorption spectra of p-terphenyl doped poly(methyl methacrylate) (PMMA) film upon laser ablation shows that no other transient species than the excited singlet and triplet states is involved. Fragmented particles were observed from 50 ns after excitation, while all morphological changes were completed in sub-ms time range.
