Abstract

A technique based on the rapid scanning capability of the video fluorometer to acquire an emission-excitation matrix (EEM) has been developed for phosphorimetry. This technique overcomes the problem of convolution of time decay with phosphorescence excitation and emission spectra by integrating the signal on target. This method also circumvents the need for very rapid acquisition of data for samples with phosphors of very short lifetimes. A phosphorescence emission-excitation matrix (PEEM) obtained in this manner permits time resolution. Sets of each time-PEEM allow a ratio deconvolution algorithm to successfully resolve mixtures of polynuclear aromatic compounds. © 1982, American Chemical Society. All rights reserved.
