Abstract

Fluorescent CdSe–CdS–Cd0.5Zn0.5S–ZnS core–shell colloidal quantum dots (cQDs) dispersed in aqueous and organic solvents have been prepared and used as scintillators for detecting ionizing radiation. Results demonstrate a linear relationship between emitted luminescence and dose–activity. These results suggest that cQDs alone could be used as liquid scintillators for specific environmental and medical applications.
