Here, for the first time these clusters are probed by time-resolved photoelectron spectroscopy and characterized in detail by density functional theory. Their validity as building blocks for cluster-assembled materials is confirmed via rigid cage-like structures facilitating three-dimensional aggregation in combination with large band gaps that are nevertheless significantly lower than any known ZnO polymorph. In addition, electron–hole pair localization in the excited state of the cluster anions combined with their structural rigidity leads to extraordinary long-lived states above the band gap virtually independent of the cluster size, defying the rule “every atom counts”.</dcterms:abstract> <dc:date rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2014-12-09T10:53:09Z</dc:date> <dc:creator>Heinzelmann, Julian</dc:creator> <dc:contributor>Proch, Sebastian</dc:contributor> <dc:creator>Lazarski, Roman</dc:creator> <dc:creator>Sierka, Marek</dc:creator> <bibo:uri rdf:resource="http://kops.uni-konstanz.de/handle/123456789/29402"/> <dc:creator>Proch, Sebastian</dc:creator> <dc:creator>Koop, Alexander</dc:creator> <dcterms:title>Cage-Like Nanoclusters of ZnO Probed by Time-Resolved Photoelectron Spectroscopy and Theory</dcterms:title> <dc:contributor>Koop, Alexander</dc:contributor> <dc:contributor>Sierka, Marek</dc:contributor> <dcterms:issued>2014</dcterms:issued> <dc:contributor>Lazarski, Roman</dc:contributor> <dc:contributor>Heinzelmann, Julian</dc:contributor> </rdf:Description> </rdf:RDF>
