Figure 1.

Normalized diffuse reflectance (converted to the K-M function, black solid line), excitation spectra (dotted lines), and normalized (to the blue emission band intensity) emission spectra (dashed lines) of UiO-66-(OH)2 in a DMF suspension. The emission spectra are normalized to the maximum of the enol emission (465 nm). The different excitation and observation wavelengths are indicated in the inset.
