The structural and magnetic properties have been investigated in the research area of solid state physics [1][2][3][4][5][6][7][8][9][10]. In the research area of electrochemical, it is known that BaPrO3 exhibits high electron-proton mixed conduction in intermediate temperature region (600~300°C) when Yb 3+ ions are substituted into Pr 4+ site [11][12][13][14].…”

The electronic structure of Yb 3+-doped BaPrO 3 (BaPr 1-x Yb x O 3-δ) has been studied by resonant photoemission spectroscopy and X-ray absorption spectroscopy (XAS). The O 1s XAS spectra exhibit that the conduction band consists of Pr 4f and Ba 5d states. The valence band is mainly composed of the O 2p states hybridized with Pr 4f and Pr 5d states. The valence band shifts to the lower binding energy side with Yb 3+ concentration. The Pr 4f state has the mixed-valent states of Pr 4+ and Pr 3+. The intensities of Pr 4+ and Pr 3+ states rapidly decrease with increasing Yb 3+ concentration. These results may contribute to the change of charge transfer from O 2p to Pr 4f states in the ground state with oxygen vacancies and Yb 3+ substitution.

“…In view of the disagreement in signs of the cubic CFPs in Ref. [2] and the other literature data [8][9][10][11], the cubic, and thus by implication the triclinic-like CFPs [2], should be treated with caution.…”

“…The local site symmetry of the four-fold coordinated Pr 4+ ions in BaPrO 3 (orthorhombic space group Pbnm) is considered as C i due to distortion of the approximated octahedral O h symmetry [2]. The cubic symmetry was used as a first approximation in the optical spectroscopy studies of Pr 4+ in BaPrO 3 [2,[8][9][10][11]. The unit cell of BaPrO 3 drawn based on the crystallographic data [12] for T = 300 K and the definition of the crystallographic axis system (x||a, y||b, z||c) as well as the four adjacent Pr-O 6 octahedra obtained from these data indicating the buckling of octahedra were presented in Fig.…”

High transparency Pr:Y2O3 ceramics: A promising gain medium for red emission solid-state lasers

Highly transparent 0.5 and 1.0 at% Pr-doped Y2O3 ceramics were fabricated by vacuum sintering plus hot isostatic pressing (HIP) treatment. The selection of suitable pre-sintering temperatures and right microstructures before HIP was critical to obtain high density of the final sintered bodies. The well-densified ceramics had pore-free microstructures with an average grain size of about 1 µm. It was also found that the charge states of the Pr ions could be changed through regulating the annealing atmospheres, resulting in different absorption and emission characteristics in the visible wavelength region. Annealing in reducing atmosphere (5% H2/95% Ar) favored the formation of Pr3+, resulting in stronger red emissions, while annealing in oxygen atmosphere led to the rise of lattice constant due to the concentration increase of oxygen interstitials. The H2/Ar-annealed 0.5 at% Pr:Y2O3 ceramics exhibited strong red emission at 600–675 nm, which may be a promising gain material for red solid-state lasers.
