Abstract
Self-trapped-exciton (STE) luminescence of quasi-one-dimensional halog en-bridged platinum complex [Pt(en)(2)] [Pt(en)(2)Cl-2](ClO4)(4) is in vestigated by femtosecond time-resolved luminescence spectroscopy. In the high energy tail of the luminescence band, a fast rise and decay a re seen, whereas around the luminescence peak energy a slow rise of ab out 500 fs is observed. This rise becomes faster at the low energy sid e of the band. These results are consistently explained by the cooling of prethermalized STEs, following the rapid self-trapping which is es timated to occur within 140 fs.
