We show the emission intensity from doped graphene nanoribbons under transverse normal illumination as a function of the incident and emitted photon energies as calculated within the (a) TB-RPA and (b,c) MDF-CEM approaches. The incident pulse has a FWHM duration of 100 fs and a peak intensity of 10¹² W m⁻², while the Fermi energy is 0.4 eV in all cases. The ribbon width is 20 nm in a and b, and 100 nm in c, giving rise to the plasmon energies indicated by the vertical dashed lines.
