In this study, Mn 2+ ions doped lithium barium fluoride single crystals (LiBaF 3: Mn 2+) with
perovskite structure were successfully prepared by a reformative Bridgman technique. A …

The origin of the spectrochemical series and the different dependence of crystal-field
splitting (10 Dq) and Racah parameters on the metal− ligand distance, R, is explored …

The study of chemical factors that influence pigment coloring is a field of fundamental
interest that is still dominated by many uncertainties. In this Article, we investigate, by means …

This work reviews new ideas developed in the last two decades which play a key role for
understanding the optical properties of insulating materials containing transition metal (TM) …

In the last 65 years the properties of Tutton salts containing Cu2+ cations have been
interpreted on the basis of elongated complexes induced by a static Jahn–Teller effect (JTE) …

Seeking to understand why the cubic centre in MgO: Cr 3+ has the same 10Dq value as
emerald, ab initio cluster and periodic supercell calculations have been performed. It is …

The applicability of the Jahn–Teller (JT) framework to 6-fold coordinated d9 ions whose local
symmetry is not strictly octahedral is explored by means of first principle calculations. Our …

Insulating CuF2 is considered a prototype compound displaying a Jahn–Teller effect (JTE)
which gives rise to elongated CuF64–units. By means of first-principles calculations together …

This work is aimed at clarifying the changes on optical spectra of Cr3+ impurities due to
either a host lattice variation or a hydrostatic pressure, which can hardly be understood by …

Serial dual-emitting single crystals LiYF 4: 0.5 Ce 3+/αMn 2+(α= 0, 0.05, 0.1, 0.3, 0.5, and
1.0) samples were synthesized by a reformative Bridgman technique. A comprehensive …
