The formation of CdS\u2013polyoxotungstate nanohybrids is confirmed by high\u2010resolution transmission electron microscopy, elemental mapping, and powder X\u2010ray diffraction analysis. Due to the strong electronic coupling between two semiconductors, the CdS\u2013polyoxotungstate nanohybrids show a narrow bandgap energy of around 1.9\u20132.7\u2005eV, thus reflecting their ability to harvest visible light. Time\u2010resolved photoluminescence experiments indicate that the self\u2010assembly between nanosized CdS and polyoxotungstate is very effective in increasing the lifetime of holes and electrons, thus indicating an efficient electron transfer between two\u2010component semiconductors. The hybridization results not only in a significant improvement in the photostability of CdS QD but also in the creation of visible\u2010light\u2010induced photochromism. Of particular importance is that the present nanohybrids show visible\u2010light\u2010driven photocatalytic activity to produce H<jats:sub>2<\/jats:sub> and O<jats:sub>2<\/jats:sub>, which is superior to those of the unhybridized CdS and polyoxotungstate. The self\u2010assembly of nanometer\u2010level semiconductor clusters can provide a powerful way of optimizing the photoinduced functionalities of each component (i.e., visible\u2010induced photochromism and photocatalysis) by means of strong electronic coupling.<\/jats:p>","DOI":"10.1002\/chem.201100583","type":"journal-article","created":{"date-parts":[[2011,7,20]],"date-time":"2011-07-20T09:34:37Z","timestamp":1311154477000},"page":"9626-9633","source":"Crossref","is-referenced-by-count":24,"title":["Self\u2010Assembly
