valence-loss spectrum (low-loss spectrum)

valence-loss spectrum (low-loss spectrum)

A spectrum in the low energy region (below ~50 eV) in an EELS spectrum is called "valence-loss spectrum (low-loss spectrum)." This spectrum enables the band gap energy (0 to 10 eV) and the plasmon energy (10 to 50 eV) to be obtained. Dielectric and optical properties of solids can be investigated from the spectrum.
