Term: excitation spectrum
https://doi.org/10.1351/goldbook.E02253

Definition:
A plot of the spectral radiant exitance or of the spectral photon exitance against the frequency (or wavenumber, or wavelength) of excitation. When corrected for wavelength dependent variations in the excitation radiant power this is called a corrected excitation spectrum.
