Optical Materials: X, 2021 The Duffy's model is reformulated for Sb 3+ and Bi 3+ in cubic chloro- and bromoelpasolites with « 0D » perovskite structure. The new equation allows calculating the energy of the first s 2 → s 1 p 1 electron transition from crystal structure data.

A Review of Synthesis, Characterization, Properties, and Applications of Double Perovskite Oxides
InorganicsDouble perovskites are represented by the formula A2BB’O6 and AA’BB’O6. These materials have been synthesized using the solid-state reaction, sol–gel, Pechini, and hydrothermal methods.

Small‐Band‐Gap Halide Double Perovskites
Angewandte Chemie, 2018 AbstractDespite their compositional versatility, most halide double perovskites feature large band gaps. Herein, we describe a strategy for achieving small band gaps in this family of materials. The new double perovskites Cs2AgTlX6 (X=Cl (1) and Br (2)) have direct band gaps of 2.0 and 0.95 eV, respectively, which are approximately 1 eV lower than ...

Optimized Effective Potential Model for the Double Perovskites Sr2-xYxVMoO6 and Sr2-xYxVTcO6
, 2011 In attempt to explore half-metallic properties of the double perovskites Sr2-xYxVMoO6 and Sr2-xYxVTcO6, we construct an effective low-energy model, which describes the behavior of the t2g-states of these compounds.

Magnetic moments of W 5d in Ca2CrWO6 and Sr2CrWO6 double perovskites
, 2005 We have investigated the magnetic moment of the W ion in the ferrimagnetic double perovskites Sr2CrWO6 and Ca2CrWO6 by X-ray magnetic circular dichroism (XMCD) at the W L(2,3) edges.

Emergence of hidden phases of methylammonium lead-iodide (CH$_3$NH$_3$PbI$_3$) upon compression [PDF]
, 2018 We perform a thorough structural search with the minima hopping method (MHM) to explore low-energy structures of methylammonium lead iodide. By combining the MHM with a forcefield, we efficiently screen vast portions of the configurational space with ...
