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

Chemistry – A European Journal, Volume 31, Issue 36, June 26, 2025.
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.

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
