Abstract

UV–Vis DRS and photoluminescence (PL) spectroscopy, combined with excitation selective Raman spectroscopy, allow us to understand the main optical and vibrational properties of a metal–organic MOF-5 framework. A O2−Zn2+ → O−Zn+ ligand to metal charge transfer transition (LMCT) at 350 nm, testifies that the Zn4O13 cluster behaves as a ZnO quantum dot (QD). The organic part acts as a photon antenna able to efficiently transfer the energy to the inorganic ZnO-like QD part, where an intense emission at 525 nm occurs.
