Excitation‐Selective Hydrochromic Upconversion in Zero‐Dimensional Metal Halides

open access: yesAdvanced Science, EarlyView.
Excitation wavelength dictates whether moisture speaks. In zero‐dimensional metal halides, the same humidity leaves the upconversion emission unchanged under 980 nm excitation yet triggers a distinct green‐to‐red shift under 1550 nm. This excitation‐selective hydrochromism, governed by the absorption at each wavelength, enables stimulus‐dependent ...
