摘要
The present invention provides a fluorescent imaging thermographic method and system for use particularly in surface temperature measurements, which are reproducible over time. The invention provides a temperature-sensitive fluorescent probe comprising a rare earth compound in an ultraviolet and fluorescence transparent medium wherein the intensity of fluorescence varies as the temperature varies, in particular, provided are probes comprising Europium(1,1,1,5,5,5-hexafluoroacetylacetone)3 for measuring temperatures greater than 24° C., and Terbium(1,1,1,5,5,5-hexafluoroacetylacetone)3 for measuring temperatures less than 24° C. The probe is applied as a layer to a surface, exposed to fluorescence-inducing energy, and emitted fluorescence measured. A ratio imaging algorithm enables the temperature at each location on the surface to be determined.
