Ce-doped Rb2 KInF6 elpasolite has the potential for tunable luminescence due to an unusual reversible redox process between the cerium and indium cations. Coupled with a deep understanding of the luminescence properties, XRD analysis and DFT calculations are used to locate the doping elements in the host lattice. The origin explanation of the charge-transfer mechanism that causes a decrease or increase in the blue-green cerium emission in opposition to the red indium emission is discussed regarding the crystallographic structure, the connection of the metallic cations and their equilibrium valence. Still detectable after nineteen years, the optical contrast created under irradiation makes this material a good candidate as photosensor for data storage.

Undoped and Dy3+‐doped barium tantalate phosphors were synthesized by the solid‐state reaction method at 1425°C. Also, 10 mol% Dy3+‐doped BaTa2O6 was sintered between 1150 and 1425°C in order to determine temperature effect on structural and luminescence properties. Afterwards, they were characterized by XRD, SEM‐EDS and photoluminescence (PL) analyses. PL spectra exhibited the excitation peaks between 300 and 440 nm. Two typical emissions were observed at 486.2 nm (blue) and 577.7 nm (yellow) due to the 4F9/2→6H15/2 and 4F9/2→6H13/2 transitions, respectively. Emission intensities increased with increasing doping concentration of Dy3+ up to 10 mol% and then decreased due to the concentration quenching effect. Moreover, depending on the increase in heat treatment temperature, the intensity of emission reached maximum at 1425°C. The calculated CIE chromaticity coordinates of phosphors located in the white light region.

“…Fluoroperovskites display rich structural chemistry, strongly ionic bonding character (due to the high electronegativity of the fluoride anions), and corresponding localized electron magnetism [1,2]. They exhibit a wide range of properties that can be utilized in, e.g., data storage, computer processors, spintronics, multiferroics, and batteries [3][4][5][6].…”

We report a synthesis method, and structural and magnetic characterization, for the fluoroperovskite NaFeF 3 . We have developed a wet-chemical method that allows preparation of large volumes of air-sensitive fluoroperovskites with high purity. NaFeF 3 has a Néel temperature (T N ) of 90 K and a Weiss constant (θ) of −124 K, corresponding to dominant antiferromagnetic interactions. Below T N , a slight difference is observed between zero-field and field-cooled samples, indicating spin canting and weak ferromagnetism. AC magnetometry supports that weak ferromagnetism is inherent to NaFeF 3 and not due to an impurity. From powder neutron diffraction data, we describe the magnetic structure precisely as a weakly canted G-type (magnetic space group Pn ma ). A ferromagnetic component is allowed in Pn ma , however, this component is too small to be confirmed on the basis of powder neutron diffraction data and may be absent in zero magnetic fields.
