Figure 3
XEOL spectra of the Gd₂O₂S:Tb³⁺ X-ray scintillator, measured under excitation at 7000–8800 eV monochromatic X-ray energies, around the host Gd L_3,2,1 edges (7243, 7930 and 8376 eV) and photoemitting Tb L_3,2,1 edges (7514, 8252 and 8708 eV). The inset figure shows a magnified spectral region around the emission line from the ⁵D₄ → ⁷F₄ transition.
