Azetidinium Lead Halide Ruddlesden–Popper Phases

A family of Ruddlesden–Popper (n = 1) layered perovskite-related phases, Az(2)PbCl(x)Br(4−x) with composition 0 ≤ x ≤ 4 were obtained using mechanosynthesis. These compounds are isostructural with K(2)NiF(4) and therefore adopt the idealised n = 1 Ruddlesden–Popper structure. A linear variation in u...

Sumario:A family of Ruddlesden–Popper (n = 1) layered perovskite-related phases, Az(2)PbCl(x)Br(4−x) with composition 0 ≤ x ≤ 4 were obtained using mechanosynthesis. These compounds are isostructural with K(2)NiF(4) and therefore adopt the idealised n = 1 Ruddlesden–Popper structure. A linear variation in unit cell volume as a function of anion average radius is observed. A tunable bandgap is achieved, ranging from 2.81 to 3.43 eV, and the bandgap varies in a second-order polynomial relationship with the halide composition.
