Abstract
Abstract A method for determining the temperature of a fluid particularly adapted to the determination of droplet temperatures. A fluorescent monomer and a quencher are added to a fluid and the monomer is excited by directing an energy source of a proper wavelength at the fluid. The excited monomer then combines with the quencher to produce a fluorescent exciplex in the fluid. The temperature of the fluid is determined by detecting the fluorescence from the excited monomer and exciplex in the fluid. The ratio of fluorescence of these species provides data from which the temperature can be determined.

Claim 1
Independent Claim
78 words
A method for determining at least one temperature of a fluid comprising: (a) adding a fluorescent monomer and an organic quencher to a fluid; (b) exciting the monomer by directing an energy source of a proper wavelength at the fluid, the excited monomer than comines with the quencher to produce a fluorescent exciplex in the fluid; and (c) determining the temperature of the fluid by detecting the relative fluorescence from the excited monomer and exciplex in the fluid.
