Oh fluorescence lifetime
Webb20 juli 2013 · Radially resolved fluorescence lifetime profiles of OH, measured 9 mm above the burner for the four different equivalence ratios, are presented with symbols in … 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.
