Coumarin 545: an emission reference dye with a record-low temperature coefficient for ratiometric fluorescence based temperature measurements.
نویسندگان
چکیده
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.

Instantaneous temperature imaging by planar laser-induced fluorescence. Effect of high laser irradiance
The temperature dependence of the fluorescence emission of certain organic dyes is utilized for measuring the temperature in liquid flows. Measurements are generally based on the assumptions that: the fluorescence signal is proportional to the intensity of the laser excitation, and the temperature sensitivity of the dye is not affected by the laser irradiance. These assumptions allow justifying...
متن کاملDual Emission Laser Induced Fluorescence For Direct Planar Scalar Behavior Measurements
In this paper, a new method of measuring scalar behavior in bulk aqueous fluid flows is presented. Using a simple ratiometric scheme, laser induced fluorescence from organic dyes can be normalized so that direct measurements of a scalar in the flow are possible. The technique dual emission laser induced fluorescence (DELIF) relies on normalizing the fluorescence emission intensity of one dye wi...

This paper presents the development and implementation of a Dual Emission Laser Induced Fluorescence (DELIF) technique for the measurement of film thickness and temperature of tribological flows. The technique is based on a ratiometric principle that allows normalization of the fluorescence emission of one dye against the fluorescence emission of a second dye, eliminating undesirable effects of...
متن کاملA twisted-intramolecular-charge-transfer (TICT) based ratiometric fluorescent thermometer with a mega-Stokes shift and a positive temperature coefficient.
The fluorescence intensity of N,N-dimethyl-4-((2-methylquinolin-6-yl)ethynyl)aniline exhibits an unusual intensification with increasing temperature, by activating more vibrational bands and leading to stronger TICT emissions upon heating in dimethyl sulfoxide. Based on the different temperature dependence at various wavelengths, as shown in the TICT fluorescence spectrum, this dye can be emplo...

Ratiometric molecular probes RP1 and RP2 consisting of a blue fluorescent coumarin and a red phosphorescent cationic iridium complex connected by a tetra- or octaproline linker, respectively, were designed and synthesized for sensing oxygen levels in living cells. These probes exhibited dual emission with good spectral separation in acetonitrile. The photorelaxation processes, including intramo...
