Abstract
A hydrochromic halide perovskite includes a CsxTbyFz halide perovskite doped with a lanthanide ion dopant, which is capable of water-induced reversible phase transformation between pristine state and wet state, and exhibits reversible change in optical emission under ultraviolet excitation. A printable pattern comprising a film of the hydrochromic halide perovskite and a method for preparing the hydrochromic halide perovskite are also addressed.
