Values of fluorescence lifetime (τ in ns) and fractional intensity (f), with their corresponding standard deviations, measured for the starch/NTA film and the NTA PrOH solutions (two concentrations). Measurements were performed using a filter with cut-on 408 nm at the excitation wavelength of 372 nm. Compare with Fig. 9.
