Fig. 3. (a) Emission spectra of CAuI6AgIn-type clusters 2–4 (n = 2, 3, 4) in the solid state at room temperature and corresponding emission photographs of 365 nm excitation (from left to right). (b) Emission spectra of clusters 2–4 in CH2Cl2 at 20 °C and corresponding emission photographs of 365 nm excitation (from left to right). (c) Emission decays of clusters 2–4 in CH2Cl2 at room temperature.
