(a) The fluorescence intensities of separate molecules (donor and acceptor) and complex in the absence and presence of TNT were measured under 390-nm laser excitation. (b) The fluorescence decay dynamics of separate molecules and the complex donor in the absence and presence of TNT. Filled circles indicate the IRF signal with a FWHM of 220 ps. (c) The wavelength dependence of the donor fluorescence decay time in the absence and presence of TNT.
