Abstract

We recorded temperahrre-dependent fluorescence spectra of nine laser dyes for their suitability for dvo-color laser-induced fluorescence (2cLIF) thermometry in liquid sprays. Due to the high temperahrre sensitivity and a large Stokes shift, coumarin 152 hrrned out to be most suited. Temperature imaging is demonstrated in an ethanol spray flame.
