Chloride Double Perovskites Doped With Sb³⁺/Er³⁺ as Stable and Effective Luminescence Material in the Vis-NIR Region. [PDF]

Chemistry
The luminescence properties of Sb3+/Er3+‐doped chloride double perovskites Cs2Ag0.4Na0.6InCl6 have been investigated across 250‐1600 nm. Structural and spectroscopic analyses have been performed using XRD, SEM, Raman, XPS, and ToF‐SIMS methods. Energy transfer from Sb3+ to Er3+ enables emission at 525, 552, 665, 805 and 1540 nm.

(Ln = La…Lu, X = F, Cl, Br, I) elpasolites

, 2021
Elpasolite crystals are very important materials, both from the applied and fundamental points of view. Those elpasolites, which contain rare earth ions with a high atomic number Z, are very much suitable for the low-cost high-performance gamma-ray ...

Structure and Stability of the Iodide Elpasolite, Cs2AgBiI6 [PDF]

, 2023
Iodide elpasolites (or double perovskites, A2B'B"I6, B' = M+, B" = M3+) are predicted to be promising alternatives to lead-based perovskite semiconductors for photovoltaic and optoelectronic applications, but no iodide elpasolite has ever been ...

Band Gap Tuneability in Antiperovskite‐Based Nitrides AE3PnN and Imides AE5Pn2(NH)2 (AE = Ca, Sr; Pn = As, Sb, Bi)

Angewandte Chemie, Volume 138, Issue 20, 11 May 2026.
A series of imide‐based defect antiperovskites AE5Pn2(NH)2 (AE = Ca, Sr; Pn = As, Sb, Bi) has been synthesized using the ammonothermal method. DFT calculations and spectroscopy revealed direct band gaps suitable for photovoltaic absorber materials. The discovered compounds can further be used as precursors for the synthesis of AE3PnN antiperovskites as

Barocaloric effect in ferroelastic fluorides and oxyfluorides [PDF]

, 2020
Using the data about the temperature - pressure phase diagram and the phase transition entropy at ambient and high pressure, intensive and extensive barocaloric effects were analyzed in the region of single and successive order-disorder phase transitions

Effect of the f-Orbital Delocalization on the Ligand-Field Splitting Energies in Lanthanide-Containing Elpasolites [PDF]

, 2006
The ligand-field induced splitting energies of f-levels in lanthanide-containing elpasolites are derived using the first-principles universal orbital-free embedding formalism [Wesolowski and Warshel, J. Phys. Chem. 1993, 97, 8050].
