Quantitative oxygen concentration imaging in toluene atmospheres using Dual Imaging with Modeling Evaluation

Forskningsoutput: TidskriftsbidragArtikel i vetenskaplig tidskrift

Abstract

Fluorescence lifetimes of toluene as a function of oxygen concentration in toluene/nitrogen/oxygen mixtures have been measured at room temperature using picosecond-laser excitation of the S-1-S-0 transition at 266 nm. The data satisfy the Stern-Volmer relation with high accuracy, providing an updated value of the Stern-Volmer slope. A newly developed fluorescence lifetime imaging scheme, called Dual Imaging with Modeling Evaluation (DIME), is evaluated and successfully demonstrated for quantitative oxygen concentration imaging in toluene-seeded O-2/N-2 gas mixtures.
