Description
We model the blueshift of the photoluminescence spectra of CdSe-ZnS nanocrystals under ultraviolet irradiation. The model is based on photo-assisted oxygen diffusion into the CdSe nanocrystal structure, which is believed to have a primary role in the observed blueshift of the photoluminescence peak wavelength by reducing the confinement core radius of the exciton wavefunction inside the CdSe nanocrystal core. We compare the predictions of this model with experimental data (copyright 2011 WILEY-VCH Verlag GmbH and Co. KGaA, Weinheim) (orig.)
