Figure 2From: The Role of Intrinsic and Surface States on the Emission Properties of Colloidal CdSe and CdSe/ZnS Quantum Dots(A) PL intensity of the three states as a function of temperature for CdSe/ZnS QDs (symbols). The same behaviour characterizes the CdSe QDs. The continuous lines are the best fit of experimental data from 15 to 60 K to the expressions obtained by solving a set of rate equations.
