Abstract

Inverse analysis of transmission spectra for triarylamine dye in acetone is presented. This analysis employed a parametric model of transmission through a sample of finite thickness, where the permittivity function was represented parametrically by a linear combination of Lorentzian functions. The results of this analysis provided estimates of the permittivity function for triarylamine dye, which can be adopted as input data to other types of models, such as those for prediction of transmission and reflectivity spectra for composites containing mixtures of dyes and other materials. In addition, this analysis demonstrated that the absorption coefficients for a dye, which were obtained by inverse analysis of transmission spectra for that dye in solution, can be validated as reasonable estimates of the absorption coefficients for that dye in fabric.
