An exciplex-based fluorescence method was employed for remote, nonintrusive, instantaneous probing of fuel droplet temperature. The fluorescence emission spectra from a droplet doped with naphthalene and TMPD were measured with an optical multichannel analyzer. The effects of ambient gas composition, such as oxygen, carbon dioxide and water vapor, ambient gas velocity, and concentrations of naphthalene and TMPD on fluorescence emission spectra were studied. The results showed that oxygen in the ambient gas was a major quencher of fluorescence and that the fluorescence emission spectra varied with concentrations of naphthalene and TMPD. It was suggested that the temperature dependency of the ratio of fluorescence intensities at two different wavelengths for a burning droplet was the same as that for a droplet evaporating in a nitrogen atmosphere.
