Azetidinium lead halide Ruddlesden-Popper phases

Working Paper
This content is a preprint and has not undergone peer review at the time of posting.

Abstract

A family of Ruddlesden-Popper (n = 1) layered perovskite-related phases, Az2PbClxBr4-x with composition 0 ≤ x ≤ 4 were obtained using mechanosynthesis. 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.
