| 摘 要： | Fluorescence lifetime provides a third independent dimension of information for the resolution of totalluminescence spectra of multicomponent mixtures.The incorporation of this parameter into theexcitation-emission matrix(EEM)by the phase modulation technique results in a three-dimensionalexcitation-emission-frequency array (EEFA).Multicomponent analysis based on the three-dimensionalEEFA brings a qualitative change for the resolved spectra,i.e.individual spectra can be uniquely resolved,which is impossible with any two-dimensional analysis.In this paper we present a method for analyzingthe EEFA.We show mathematically that with the three-dimensional analysis of the EEFA individualspectra and lifetimes can be obtained.Our algorithm is developed in mathematical detail and isdemonstrated by its application to a two-component mixture.

| Abstract: | Fluorescence lifetime provides a third independent dimension of information for the resolution of total luminescence spectra of multicomponent mixtures.The incorporation of this parameter into the excitation-emission matrix(EEM)by the phase modulation technique results in a three-dimensional excitation-emission-frequency array (EEFA).Multicomponent analysis based on the three-dimensional EEFA brings a qualitative change for the resolved spectra,i.e.individual spectra can be uniquely resolved, which is impossible with any two-dimensional analysis.In this paper we present a method for analyzing the EEFA.We show mathematically that with the three-dimensional analysis of the EEFA individual spectra and lifetimes can be obtained.Our algorithm is developed in mathematical detail and is demonstrated by its application to a two-component mixture. |
