Since the formation of color centers is closely related to the optical creation of electron-hole pairs the sensitivity of the photochromic effect in W03 is limited to energies above its band-gap energy of 3.25 eV, corresponding lo the near-uluaviolet range. We will demonstrate that in case of a thin cadrnjum sulfide (CdS) layer underneath the tungsten oxide film the sensitivity of photochromism is shifted into the visible range. This result is interpreted in terms of charge carrier injection from the CdS into the WO3. Apart from a more detailed understanding of the photochromic effect this may have also relevance for technical applications.</dcterms:abstract> <dcterms:bibliographicCitation>First publ. in: Applied Physics Letters 68 (1996), 20, pp. 2834-2836</dcterms:bibliographicCitation> <dspace:hasBitstream rdf:resource=""/> <dcterms:isPartOf rdf:resource=""/> <dcterms:rights rdf:resource=""/> <void:sparqlEndpoint rdf:resource="http://localhost/fuseki/dspace/sparql"/> <dc:format>application/pdf</dc:format> <dspace:isPartOfCollection rdf:resource=""/> <dc:contributor>Bechinger, Clemens</dc:contributor> <dc:rights>Attribution-NonCommercial-NoDerivs 2.0 Generic</dc:rights> <dcterms:issued>1996</dcterms:issued> <dc:contributor>Wirth, Eckehard</dc:contributor> <dc:creator>Leiderer, Paul</dc:creator> <bibo:uri rdf:resource=""/> <dc:date rdf:datatype="">2011-03-24T17:51:18Z</dc:date> <dcterms:hasPart rdf:resource=""/> </rdf:Description> </rdf:RDF>
