Self-assembled organic-inorganic CH<sub>3</sub>NH<sub>3</sub>PbI<sub>3</sub> perovskite microwires (MWs) upon humidity exposure along several weeks were investigated by photoluminescence (PL) spectroscopy, Raman spectroscopy, and X-ray diffraction (XRD). We show that, in addition to the common perovskite decomposition into PbI<sub>2</sub> and the formation of a hydrated phase, humidity induced a gradual PL redshift at the initial weeks that is stabilized for longer exposure (~ 21 nm over the deg ...[more]
