Figure 2.

(A) Normalized emission spectra of UiO-66-(OH)2 in powder form at different excitation wavelengths (indicated in the figure). (B) Magic-angle emission decays of UiO-66-(OH)2 in powder form. The sample was excited with a 371 nm pulsed laser and probed at the indicated wavelengths. The solid black lines correspond to the fits of the decays using a multiexponential function, while the IRF is the instrumental response function.
