Double Salts Iodide Scintillators: Cesium Barium Iodide, Cesium Calcium Iodide, and Barium Bromine Iodide

Crystal Research and Technology, 2013
AbstractIn this study we review the state‐of‐the‐art for double salt iodide scintillators, in particular cesium barium iodide (CBI), cesium calcium iodide (CCI) and barium bromine iodide (BBI), as well as report on their scintillation and optical properties.

Molecular Structures of Perfluoromethyl Iodide, Perfluoroethyl Iodide, and Perfluoroisopropyl Iodide

The Journal of Chemical Physics, 1972
The molecular structures of three fully halogenated alkanes have been investigated by electron diffraction. The following rg parameters were determined for CF3I: C–I=2.101±0.009 Å; C–F=1.344±0.004 Å; and ∠FCI=111.3°±0.4°. For CF3CF2I: C–I=2.142±0.023 Å; C–F=1.338±0.004 Å; C–C=1.523±0.027 Å; with ∠CCI=113.4°±0.8°; ∠CCF=109.9°±0.8°; and ∠ICF=109.4°±1.0°.

A Cation-Exchange Approach for the Fabrication of Efficient Methylammonium Tin Iodide Perovskite Solar Cells.

Angewandte Chemie, 2019
Tin-based halide perovskite materials have been successfully employed in lead-free perovskite solar cells, but the overall power conversion efficiencies (PCEs) have been limited by the high carrier concentration from the facile oxidation of Sn2+ to Sn4+ .
