Fluorescence quantum yields are used to quantify the efficiency of the emission process. In spite of the importance of these data, experimental directions for their acquisition are rarely given. A general procedure for determining the relative fluorescence quantum yield of solutions is described here, drawing attention to the many pitfalls that students may encounter. Starting materials are common yellow and pink highlighter pens.
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.
