Engineered Biographical Defects in Two-Dimensional Nonanediaminium Lead Iodide Perovskites: From Synthesis to Reversible Photodegradation

Abstract The choice of lead precursor (PbO versus PbI2), the Pb:diamine stoichiometric ratio, and the crystallization regime influence the defect landscape and optical stability of the layered hybrid perovskite (NonDA)PbI4. Diffuse reflectance spectroscopy, X-ray photoelectron sp...
