Abstract

An apparatus is described which enables the rapid recording of time-resolved emission spectra on a nanosecond time scale. The instrument permits detailed study of the time-dependent photophysical processes occurring in many polymer systems. The technique has been used to investigate the kinetics of excimer formation in methylene chloride solutions of polystyrene and poly(1-vinylnaphthalene). Unambiguous evidence for excimer dissociation is observed in poly(1-vinylnaphthalene) but the process appears unimportant in solutions of polystyrene.
