We synthesized CsBr nanoplatelets and controlled their size and shape using HBr and tetrabutylammonium bromide (TBAB) as bromine precursors, obtaining hexagonal and rectangular plates, respectively. The phenomena were elucidated by density functional theory calculations, which indicated that the formation of...

Cesium bromide is a colorless crystal with the formula CsBr. It is a moderately water soluble crystalline Cesium source that decomposes to Cesium oxide on heating. Most metal bromine compounds are water-soluble and are used in water treatment, chemical analysis, and ultra-high purity for certain...
Novel lead-free non-perovskite blue-emitting cesium bromine (CsBr) QDs have been prepared using a ligand-assisted re-precipitation method. A high photolumi... T Li,M Qiao,X He,... - 《Chemical Communications》 被引量: 0发表: 2023年 Controlled synthesis of highly stable lead-free bismuth...
These results suggest that Nd doping is more efficient in the stabilization of the perovskite structure than partial replacement of iodine with bromine. Microstructure observations reveal the existence of two different product formation mechanisms depending on the mechanical properties of reactants. The ...

These completely amine free CsPbBr 3 perovskite NCs synthesized using bromine-rich condition exhibit good stability and durability for more than three months in the form of colloidal solutions and films respectively. More importantly, this work presents an open atmospheric stable CsPbBr 3 NCs films ...

Although bromine in CsPb(Br/Cl)3 sample also has a single charge state, however, the FWHM of the Br3d5/2Br3d5/2 and Br3d3/2Br3d3/2 peaks is increased and the peaks are not resolved. Apparently, this is due to the fact that the nearest environment of bromine atoms in the ...
