Abstract

The emission intensities of coumarin 545 solution exhibit a low temperature dependence, with a record-low temperature coefficient of only ∼0.025% per °C. This monomer-aggregate coupled fluorescence system can be used for ratiometric temperature measurements with high spatial and temporal resolutions; three different working modes have been demonstrated.
