“…Finally, the spectrum of Tb 3+ 3d spectrum is consistent with the XPS spectra reported for Tb 2 O 3 . 85,86 At this point we can conclude that in all synthesised films show correct R 3+ (i.e. Er 3+ , Yb 3+ , Tb 3+ ) and Ti 4+ oxidation states.…”

Frustrated rare-earth pyrochlore titanates, Yb 2 Ti 2 O 7 and Tb 2 Ti 2 O 7 , have been proposed as promising candidates to realize quantum spin ice (QSI). Multiple exotic quantum phases, including Coulombic ferromagnet, quantum valence-bond solid, and quadrupolar ordering, have been predicted to emerge in the QSI state upon the application of a (111)-oriented external magnetic field. Here, we report on the primal successful layer-by-layer growth of thin films of frustrated quantum pyrochlores, R 2 Ti 2 O 7 (R = Er, Yb, and Tb), along the (111) direction. We confirm their high crystallinity and proper chemical composition by a combination of methods, including in-situ RHEED, x-ray diffraction, reciprocal space mapping, and x-ray photoelectron spectroscopy. The availability of large area (111)-oriented QSI structures with planar geometry offers a new complementary to the bulk platform to explore strain and magnetic field dependent properties in the quasi-2D limit.

“…In the 3d region, the Tb3d 3/2 peak overlaps with the Ce3p 1/2 peak, and the two 1241.96 and 1245.19 eV energy peaks were assigned to the Tb3d 5/2 multiplet splitting, corresponding to the 3d 9 4f 9 and 3d 10 4f 8 final states. As the bond energies are slightly higher than for corresponding metal or oxides [ 26 , 27 ], and fluorine electronegativity is higher than for oxides, the peaks were assigned to the Tb-F bonds, due to the Tb 3+ incorporation in the CeF 3 matrix.…”

In this study, we report on the structural, magnetic, and optical properties of Tb3+-doped CeF3 nanocrystals prepared via a polyol-assisted route, followed by calcination. X-ray diffraction analysis and electron microscopy investigations have shown the formation of a dominant Ce0.75F3 nanocrystalline phase (of about 99%), with a relatively uniform distribution of nanocrystals about 15 nm in size. Magnetization curves showed typical paramagnetic properties related to the presence of Ce3+ and Tb3+ ions. The magnetic susceptibility showed a weak inflexion at about 150 K, assigned to the cerium ions’ crystal field splitting. Under UV light excitation of the Ce3+ ions, we observed Tb3+ green luminescence with a quantum yield of about 20%.

“…However, terbium sesquioxide easily oxidized into Tb 4 O 7 without magneto-optical properties, which considerably affect the performance of this kind of material [13]. Furthermore, terbium oxide undergoes a reversible phase transition from the C-type cubic phase to the B-type monoclinic phase when the temperature exceeds 1600 • C. [14,15].…”

In this paper, (Tb0.7Lu0.3)2O3 magneto-optical transparent ceramics with different ZrO2 doping levels (0~5 at%) were prepared by hydrogen sintering and sequential HIP technique using ZrO2 as a sintering aid. The effect of ZrO2 doping content on the microstructure and optical properties of (Tb0.7Lu0.3)2O3 ceramics was analyzed. We found that the optimal doping content of ZrO2 was 3 at%. The transmittance of 3 at% ZrO2-doped (Tb0.7Lu0.3)2O3 ceramics at the wavelength of 1064 nm was 74.84 %, and the Verdet constant was approximately 275.28 rad·T−1·m−1 at the wavelength of 650 nm.
