摘要：
In thin pyrene films deposited on a silicon substrate the high temperature crystalline phase is found to persist down to He-temperature. In optical CW and ps time-resolved measurements spectral characteristics and excited state dynamics of this phase are investigated in a largely extended temperature range (4.2-300 K). The quantitative analysis ultimately confirms our concept of a two-step excimer formation process in pyrene via the metastable B-state being observed in the whole temperature range. © 1990.
