      Photoluminescence (PL) spectroscopy was used to characterize   nanoscale ZnO impurities, amine-donor charge-transfer exciplexes,   and framework decomposition in samples of MOF-5 prepared by   various methods. The combined results cast doubt on previous   reports describing MOF-5 as a semiconductor and demonstrate that   PL as a tool for characterizing MOF purity possesses advantages   such as simplicity, speed, and sensitivity over currently   employed powder XRD MOF characterization methods.
