We have reported that the iodine element can be replaced with chlorine one in the thin-film system of lead iodide-based 2D layered hybrid perovskite (2D LHP) fabricated by the intercalation method, when it is exposed to vapor of hydrochloric acid. Here we report that iodine element can be also replaced with bromine one, when the lead iodide-based 2D LHP film is exposed to vapor of hydrobromic acid.
