The validity on the cubic crystal industry approximation for your interpretation with the magnetic resonance properties in the Er(three+) ion in crystal fields with tetragonal and trigonal symmetry is examined and it's shown which the broadly accepted CCF approximation can cause a misinterpretation of the bottom condition Stark stage as well as lattice coordination of the ion.

During the cubic stage, the CL emission peak at 221 nm a little redshifts to 226 nm because the strain will increase from 0.one GPa to three.7 GPa. The shift to for a longer time wavelengths on the CL peak (stable black circles in Fig. 7b) is consistent with the decrease within the core−valence bandgap (reliable grey circles in Fig. 7b; Desk one) for cubic BaF2 stressed. The depth of CL emission seems to be continual as being the tension is amplified. At three.seven GPa, where BaF2 exists in each the cubic and orthorhombic phases, the luminescence emission depth is weakened. Within the orthorhombic phase, the luminescence emission depth seems to generally be steady, albeit weaker in comparison to the intensity from the cubic stage, as being the tension will increase. Curiously, the luminescence peak Evidently shifts to an extended wavelength via the section transition from your cubic phase into the orthorhombic period (stable circles with strong traces in Fig. 7b, replotted as good circles in Fig. 7g; Table two). At an applied strain of 5.0 GPa, a optimum shift to 238 nm is observed. This shift is consistent with the read more decrease while in the Main−valence bandgap in the orthorhombic stage due to the downshift with the valence band (sound orange circles with dashed traces in Fig. 7b; Desk 1). The observed broadening of your luminescence emission, specifically in the orthorhombic stage, can be attributed to your enlargement of the valence bandwidth because the stress raises. As proven in Table one, the width of your valence band (ΔEv) will increase monotonically given that the pressure will increase. At substantial tension, the strengthened crystal field can induce higher band splitting and greatly enhance electron‒phonon coupling37. Without a doubt, earlier works have noted identical broadening in valence−conduction band photoluminescence emission38,39,40, but This can be the initial report on broadening of core−valence band luminescence.
