Photon Time-of-Flight Fluorescence Spectroscopy through an Optical Fiber

Abstract
The feasibility of time-domain luminescence spectroscopy using an optical fiber as a dispersive element has been demonstrated for the fluorescence of hematoporphyrin in dioxane. A cw mode-locked Ar+ laser was used for the excitation, and a time-correlated single-photon counting technique for the detection. The effects of several time-broadening factors and possible applications of this spectroscopic method are discussed.
