摘要：
We report on direct observation of spatial and optical luminescence switching (on and off condition) due to collapse of the coupling conditions of quantum dots (QDs) pair. In particular, one could observe that the relative intensities between two adjacent luminescence peaks and spatial images of individual QDs located closely nearby in a high-density self-assembled QD structure underwent a reversible change with respect to an external electric field.
