“…The diode emission observed at around 900 nm corresponds to the transition of 4 F 3/2 → 4 I 9/2 . It was attributed to the electronic transitions from the lowest 4 F 3/2 crystal field component to the ground manifold [ 34 ]. We noted the observation of only two 4 I 9/2 Stark levels instead of the expected five.…”

Rare earth element-doped Bi0.5Na0.5TiO3–BaTiO3 (BNT–BT–RE) polycrystalline thin films were processed on a platinized substrate by chemical solution deposition. The microstructure, dielectric, and ferroelectric properties were investigated for all prepared films. It was found that the incorporation of rare earth elements into the BNT–BT matrix increases both the dielectric constant and the breakdown strength while maintaining low dielectric losses, leading to an enhancement of the energy storage density to Wrec = 12 and 16 J/cm3 under an effective field of E = 2500 kV/cm, for Nd- and Dy-based films, respectively. The optical properties of films containing the lanthanide element were investigated and the obtained results bear interest for luminescence applications. The simultaneous appearance of ferroelectric and optical properties in the system under investigation is very promising for advanced optoelectronic devices.

“…Besides, other oxides like tetragonal tungsten bronzes (TTB) are particularly promising for numerous physical properties, such as ferroelectricity, − piezoelectricity, , optic properties, , and photocatalytic activities. − Despite that TTB phases in K–Ta–O and K–Nb–O systems are reported in the literature, − no work has been published until now on TTB phases in the K–Ta–Nb–O system, neither as bulk nor as supported nanostructure.…”

International audienceK−Ta−Nb−O tetragonal tungsten bronze phase was grown on (11̅02) Al2O3 (R-plane sapphire) by pulsed laser deposition. The microstructure, structure, and chemical composition of the deposit were studied by scanning electron microscopy, X-ray diffraction, energy-dispersive X-ray spectrometry, and transmission electron microscopy. The crystal structure was solved by precession electron diffraction as being tetragonal tungsten bronze-type structure with space group P4/mbm, refined cell parameters a = 12.537 ± 0.003 Å, c = 3.975 ± 0.001 Å, and composition K5.06(Ta0.57Nb0.43)10.99O30. The tetragonal potassium tantalum niobate growth follows two modes with respect to the substrate surface: (i) as single vertical right parallelepiped-shaped nanorods (50 to 100 nm wide and up to 1 μm in length) along the [001] direction and (ii) as in-plane attached crystals along the ⟨310⟩ direction. These two growth modes are understood as being governed by the plane termination of the substrate. This new phase is of potential interest due to the physical (dielectric, catalytic, etc.) properties evidenced for tetragonal tungsten bronze phases in numerous systems
