## excitation-emission spectrum

https://doi.org/10.1351/goldbook.E02249
The three-dimensional spectrum generated by scanning the @E02060@ at incremental steps of @E02248@ @W06659@ ($$x$$ axis = emission @W06659@, $$y$$ axis = excitation @W06659@, $$z$$ axis = emission flux) is called a (@F02453@, @P04569@) excitation-@E02060@ (or EES). The spectra are particularly useful for investigating samples containing more than one emitting species. Corrected EES are obtained if (a) the emission is corrected for instrumental response with @W06659@, and (b) the exciting radiation flux in photons $$\text{s}^{-1}$$ is held constant for all excitation wavelengths.
