Abstract
Crystalline materials of the compositions Cs4SnBr6, CsSnBr3, and CsBr-Sn (0.1 mol %) are investigated using x-ray diffraction and luminescent methods. The formation of the CsSnBr3 phase is found to occur in metastable Cs4SnBr6 and CsBr-Sn. It is established that the CsSnBr3 crystalline phase in the Cs4SnBr6 metastable phase is a more stable compound as compared to the CsSnBr3 bulk crystal, which undergoes oxidation and hydration in air.
