Probing the “Dark” Fraction of Core-Shell Quantum Dots by Ensemble and Single Particle pH-Dependent Spectroscopy
The optical properties of core-shell CdSe-ZnS quantum dots (QDs) are characterized by complex photophysics leading to difficulties in interpreting quantitative measurements based on QD emission. By comparing the pH dependence of fluorescence of single QDs to that of an ensemble, we have been able to...
