Webb14 apr. 2024 · Then, the fluorescence lifetime has aroused researchers’ attention to monitor of ER viscosity to improve the drawbacks based on intensity. Yu et.al have developed an iridium (III) complex sensitive to viscosity to visualize viscous changes with fluorescence lifetime imaging microscope (Figure 13A) .
WebbUsing excitation pulses of ∼30-ps duration and a fast photomultiplier detector, effective fluorescence lifetimes of the A-stateof formaldehyde after excitation at 355 and 339 nm have been measured in the preheating zone of an atmospheric pressure, premixed methane/air flame. The fluorescence lifetimes were determined as a function of height … WebbThe fluorescence lifetime of the ATTO dyes is typically in the range of nanoseconds (10 -9 s). For our catalogue, the values for the carboxy derivative in aqueous solution (PBS, pH 7.4) at 22 °C were determined using the method of "time-correlated single photon counting" described below.
