Abstract

We apply the side-illumination fluorescence (SIF) measurement to determine the linear absorption spectrum in the fluorescence emission range and to study the excited states of dye molecules in polymer fibers. These studies demonstrate that the dye is the main contributor to light absorption in the 720–840-nm range in squaraine-dye-doped polymer fibers and reveal a J-like aggregate absorption spectrum in the 780–810-nm range. We also determine that a two-level model, which accounts for inhomogeneous broadening, describes the dominant excited state of poly(methyl methacrylate) fibers doped with PSQ and HSQ dyes more effectively than does the standard Lorentzian or Gaussian two-level model. We conclude that the SIF method is a useful, nondestructive, and accurate method for measuring off-resonance absorption.
