Abstract:An intense nanosecond pulse of light is used to create electron-hole pairs in small CdS crystallites (containing ca. 10
2
atoms) suspended in a liquid. Electronic processes within the crystallite are monitored by measuring the changes of oxidation state of a redox indicator partitioned between the crystallite surface and the bulk liquid. The observed time course of these changes is analysed by the method of competition kinetics, and numerical values of key microscopic parameters (recomb… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
