“…For the single doped films, the results obtained are in agreement with previous reports [21], reaching the best luminescent emission with 5 at% (Eu) and 10 at% (Tb); a concentration quenching is observed for higher doping concentration in both cases. Fig.…”

“…The outer 5s and 5p shells shield the f electrons from the influence of external forces and, as a result, the emission spectra consist of relatively sharp lines. Although the f-f transitions of lanthanide ions are, in principle, forbidden, the crystal field surrounding the rare earth ions relaxes the selection rules so that luminescence emission can be observed even at room temperature [23].…”

The structural, magnetic and luminescence properties of praseodymium-doped zirconia powders of compositions Pr0.03Zr0.97O2 and Pr0.05Zr0.95O2 synthesized by a sol–gel process have been investigated. X-ray diffraction patterns indicate that these materials crystallize in a tetragonal fluorite-type structure. Scanning electron microscopy shows that the powders exhibit an agglomerated microcrystalline structure and the grain size may be in the order of 5–20 µm. The study of the magnetic properties of these doped metal oxides indicates a Curie–Weiss behaviour in the temperature range (100–300) K that allow us to estimate an effective magnetic moment of 3.51 μB, which indicates the presence of Pr3+ in the grown samples. Cathodoluminescence spectra recorded at temperatures between 85 and 295 K show emission peaks that can be attributed to transitions between different states within the 4f2 configuration of Pr3+ ions incorporated in the zirconia crystal lattice. Thermoluminescence measured at temperatures ranging from 373 to 773 K and at 550 nm wavelength show an intense and broad peak around 653 K for the Pr-doped zirconia which is not observed in the undoped material.

“…2. The emission bands observed in the spectra were deciphered from the literature [8,11,[17][18][19]. The spectrum of the 1-Eu sample exhibited bands associated with transitions from the 5 D 0 Eu 3+ levels to the 7 F 1,2,3 and the transition band 5 D 1 − 7 F 2 .…”

In this work, stabilized f-ZrO2 ceramic samples with the compositions of (Zr0.82Y0.09Eu0.09)O1.91, (Zr0.82Y0.09Tb0.09)O1.91 and (Zr0.82Y0.09Eu0.045Tb0.045)O1.91 were studied. The elemental composition was studied by electron probe microanalysis, and the luminescent properties were studied by local cathodoluminescence (CL). An analysis of the Eu3+ CL spectra confirmed the stabilization of the cubic phase in ceramics at room temperature. The study of the obtained CL spectra, the 5D4-7F5Tb3+ band luminescence decay kinetics, CL images and excitation spectra showed europium sensitization by terbium in (Zr0.82Y0.09Eu0.045Tb0.045)O1.91. Keywords: f-ZrO2, Eu3+, Tb3+, Ceramics, Sensitization, Cathodoluminescence
