Exciplex Fluorescence Imaging

The development of efficient combustion systems with reduced emissions can be brought about by having a clear understanding of the fuel air mixing ratios in the combustion chamber. Concentration distributions of the liquid and vapour phases of the fuel can be imaged by 

Exciplex formation occurs only in the liquid phase, where a green emission occurs on irradiation, while in the vapour phase a blue emission is observed because of the monomer. Using careful calibration techniques it is possible to perform accurate concentration measurements of the fuel/air mixtures.
