Fig. 4: Experimental and theoretical wavelength-delay maps of the CL response of the sample for EDPHS and electron beam excitations.

a (Top) Experimental and (Bottom) theoretical CL intensity spectra versus the delay \(\tau\) between the EDPHS radiation and the electron arriving at the sample. b Measured CL intensity integrated over the entire angular range at depicted delays. The EDPHS radiation is indicated by the green line. The CL signals are taken from the positions marked in the inset of Fig. 2a. c Logarithm of the (Left) measured and (Right) calculated CL intensity (\({\Gamma }^{{{\rm{CL}}}}\)) of three main emission wavelengths versus the delay \(\tau\). An exponential function (solid lines) is fitted to the data to obtain the corresponding damping times \({{{\rm{\tau }}}}_{{{\rm{d}}}}\) for each wavelength. Source data are provided as a Source Data file.
