DOI: 10.1016/j.materresbull.2016.08.052
Abstract: Abstract CsSn1−xPbxI3 (0.0 ≤ x ≤ 1.0) powders were prepared by self-organization process in aqueous solutions. After annealing in nitrogen (T = 270 °C, t = 8 h) the orthorhombic B-γ-CsSnI3 crystalline structure (space group Pnma) for 0.0 ≤ x ≤ 0.1 is observed. For x ≥ 0.3, the X-ray pattern… read more here.
