From: Optical Characteristics of ZnS Passivated CdSe/CdS Quantum Dots for High Photostability and Lasing
Two-dimension contour plot of emission wavelength verses excitation wavelength for (a) CdSe/CdS QDs and (b) CdSe/CdS/ZnS QDs. The color represents the normalized intensity of emission. (c) Normalized PL intensity (in log scale) of the samples with time.
