Abstract
The performance characteristics of a series of new excimer pumped ultraviolet dyes are presented.
Chemical structure modifications which influence dye performance are discussed. An evaluation of
several alternative solvents shows that p-dioxane remains the solvent of choice based on dye performance.
The influence of the cover gas in the dye circulator was examined and results are presented to show how
dye performance can greatly depend on this factor.
