Temperature phase transitions in Rb2KRe3+F6 elpasolites - Raman spectroscopy study

Materials and Devices, 2021
Phase transitions in crystals of fluorine-containing elpasolites are investigated by Raman scattering spectroscopy. It was found that lattice instabilities in these crystals are induced by soft mode condensations, while restorations of these modes in ...

(INVITED) Revisiting Duffy's model for Sb3+ and Bi3+ in double halide perovskites: Emergence of a descriptor for machine learning

Optical Materials: X, 2021
The Duffy's model is reformulated for Sb3+ and Bi3+ in cubic chloro- and bromo-elpasolites with « 0D » perovskite structure. The new equation allows calculating the energy of the first s2 → s1p1 electron transition from crystal structure data. The Stokes

Influence of 10 nm Hole and Electron Transport Layers on Enhancing the Efficiency of Elpasolite Solar Cell (ESC) With Dual Light Active Layers for Nanostructured Photovoltaic Applications

IEEE Access
Elpasolites are expected to be promising photovoltaic semiconductor alternatives to lead-based perovskite semiconductors. Concern over the stability and toxicity of lead halide perovskites has led to an increase in interest in the environmental friendly ...

The Rebirth of Elpasolites as Halide DoublePerovskites: From Theory to Potential Applications

Advanced Photonics Research
This perspective highlights the change in scientific focus after the past millennium from basic science to application. It follows the history of elpasolites, which were redesignated as halide double perovskites from the research focus about 8 years ago.
