Fluorescence Decay of Pyrene in a Hydrogenated Pyrene Matrix

Abstract

Pyrene, 4,5-dihydropyrene and 4,5,9,10-tetrahydropyrene have been found to form a true solid solution over a range of composition. The measured fluorescence decay lifetime of pyrene in a hydrogenated pyrene matrix has been found to depend on the wavelength at which the emission is monitored, but not on the wavelength of excitation.
