Abstract

The strain-effects on sizes and emission energies of ZnSe/ZnS quantum dots (QD) were discussed. It was found that the initial strain in the ZnSe QD layer was altered by adjusting the thickness of the ZnS buffer. Consistent blueshift of the ground-state emission from four monolayer ZnSe QD were also observed. Analysis shows that the band-gap engineering was possible through the strain modification.
