From: Crystal-field mediated electronic transitions of EuS up to 35 GPa
(a) Pressure dependence of the optical transmittance in EuS in the 0–25 GPa range at room temperature. The spectral range spans 0.05–0.5 eV and 0.74–3 eV. (b) Experimental up-stroke/downstroke (black/orange symbols) and calculated (red symbols) represent the direct band gap width at the X-point. Lines are guides to the eye.
