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.

Elpasolite scintillators. [PDF]

, 2012
This work was funded by the U.S. Department of Energy Office of Nonproliferation Research to develop elpasolite materials, with an emphasis on high-atomic-number rare-earth elpasolites for gamma-ray spectrometer applications. Low-cost, high-performance gamma-ray spectrometers are needed for detection of nuclear proliferation.

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

Turn Broad Into Narrow: Understanding the Pr3+ → Gd3+ Energy Transfer in Cs2NaYCl6

Advanced Optical Materials, Volume 14, Issue 22, 12 June 2026.
The energy transfer processes of Pr3+ in elpasolite‐like Cs2NaY1‐xGdxCl6: 1mol%$1 \,\mathrm{mol}\%$ Pr3+ is investigated by steady‐state and time‐resolved spectroscopy. An analysis of the multiexponential decays in the framework of the shell model of energy transfer suggests an occupation of both the Y and Na sites by Pr3+ in this host.

Phases of Anionic Ordering in Elpasolite Structures (Ordered Perovskites

Journal of Siberian Federal University. Mathematics & Physics, 2016
The 108 dissymmetric phases were obtained as a result of X anions ordering in elpasolite structure A2BB ′ X6 (ordered perovskite) using group theoretical methods. The critical order parameters which transform according to the irreducible representations of 􀀀 and X points of Brillouin zone of O5 h—Fm 3m space group were considered only.

The Anionically All‐Boron‐Based Anti‐Perovskites Cs3[BH4][B12H12] and Cs3[BF4][B12H12]

Zeitschrift für anorganische und allgemeine Chemie, Volume 652, Issue 3, 25 February 2026.
The anionically all‐boron‐based colorless anti‐perovskites Cs3[BH4][B12H12] and Cs3[BF4][B12H12] can be obtained by isothermal evaporation from aqueous solutions of the underlying pseudo‐binary components Cs2[B12H12] and Cs[BH4] or Cs[BF4]. At ambient conditions, Cs3[BH4][B12H12] crystallizes trigonally (R3¯$\overline{3}$m) and transforms reversibly ...

Bi–Sb Co‐Alloying Tunes Photoexcited State Dynamics in (4FPEA)4AgBi1−xSbxI8 Layered Double Perovskites through Structural Confinement

Advanced Optical Materials, Volume 13, Issue 36, December 19, 2025.
Lead‐free double perovskites are emerging alternatives to lead‐halide analogues, leveraging low toxicity and highly tunable chemical compositions. These materials possess unique carrier dynamics, often governed by self‐trapped exciton (STE)‐mediated recombination.

Filling Voids: Cubic Carbodiimide Nitride Nitridometalates (Ba6Nx)2[MN4][CN2]6 of M = Zr, Hf, Nb, Ta, Mo, and W

Zeitschrift für anorganische und allgemeine Chemie, Volume 651, Issue 17, November 25, 2025.
The crystal structures of (Ba6Nx)2[MN4][CN2]6 (left) and “ideal” 2 × 2 × 2 Perovskite (right) show similar linkage patterns despite differently shaped coordination polyhedra. Cubic carbodiimide nitride nitridometalates (Ba6Nx)2[MN4][CN2]6 of M = Zr, Hf, Nb, Ta, Mo, and W are synthesized by various high‐temperature reactions and their respective crystal

Deep Seek to the Excited States: A Thermally‐Activated Jahn–Teller Effect Achieves Superior Sensitivity for Thermometry at Cryogenic Temperature

Advanced Optical Materials, Volume 13, Issue 32, November 14, 2025.
A Sb3+‐activated bismuth‐based halide single crystal shifts the onset temperature by ≈200 K. The confluence of the spin‐orbit interaction and the dynamic Jahn–Teller effect is responsible for maximizing the opposite emission changes at different temperatures. A high relative sensitivity (Sr) value of 18.9 % K−1 is obtained at 77 K.
