摘要：

This paper reports on fluorescence microscopy and spectroscopy of single terrylene molecules embedded in p-terphenyl at room temperature. The basic photophysical parameters of this crystalline host/guest system such as photostability, single-molecule emission rates and the properties of dispersed fluorescence spectra are reported. The stability of the single-molecule signals allowed the direct observation of singlet-triplet quantum jumps at room temperature, by means of which the underlying intersystem crossing rates can be investigated. The results of earlier investigations at Liquid-helium temperatures an reviewed briefly where appropriate. The properties of terrylene in p-terphenyl are also compared to those of other host/guest systems at room temperature. (C) 1999 Elsevier Science B.V. All rights reserved.
