One way to balance these competing effects is by forming multishells and\/or gradient\u2010alloy shells. However, this introduces multiple interfaces, and their relative effects on quantum yield and blinking are not yet fully understood. Here, we undertake a systematic, comparative study of the addition of inner shells of a single component versus gradient\u2010alloy shells of cadmium\/zinc chalogenides onto CdSe cores, and then capping with a thin ZnS outer shell to form various core\/multishell configurations. We show that architecture of the inner shell between the CdSe core and the outer ZnS shell significantly influences both the quantum yield and blinking dynamics, but that these effects are not correlated\u2014a high ensemble quantum yield doesn\u2032t necessarily equate to reduced blinking. Two mathematical models have been proposed to describe the blinking dynamics\u2014the more common power\u2010law model and a more recent multiexponential model. By binning the same data with 1 and 20\u2005ms resolution, we show that the on times can be better described by the multiexponential model, whereas the off times can be better described by the power\u2010law model. We discuss physical mechanisms that might explain this behavior and how it can be affected by the inner\u2010shell architecture.<\/jats:p>","DOI":"10.1002\/cphc.201500868","type":"journal-article","created":{"date-parts":[[2015,12,23]],"date-time":"2015-12-23T02:01:36Z","timestamp":1450836096000},"page":"731-740","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Influence of the Inner\u2010Shell Architecture on Quantum Yield and Blinking Dynamics in Core\/Multishell Quantum Dots"],"prefix":"10.1002","volume":"17","author":[{"given":"Pooja","family":"Bajwa","sequence":"first","affiliation":[{"name":"Department of Chemistry and Biochemistry University of Arkansas  345 N.
