Abstract

The effect of increasing annealing times on the emission energies and dot densities of ZnSe/CdSe quantum dots has been studied. Ensemble PL carried out at 77 K demonstrates the energy shift of the main peak attributed to fractional monolayer islands, which is due to annealing. µPL conducted at 4 K was then used to study the increased spectral separation of the emission energies from SK dots. Finally, ex-situ AFM measurements of two samples, showed a reduction in the Stranski-Krastanow dot density of approximately one order of magnitude due to annealing. © 2006 WILEY-VCH Verlag GmbH & Co.
