Abstract
Highly monodisperse CdSe quantum dots 1.8 nm in size were synthesized capped with surface monolayer of 1-thioglycerol. The optical absorption of thin films of matrix free close- packed and isolated in PMMA matrix quantum dots was studied at various electric field biases. The broadening and red shift of optical transitions in close-packed ensemble against isolated is attributed to the formation of collective electronic submini-bands between interacting nanocrystals. The reversible collapse of collective electronic subminibands has been achieved by applying of strong electric field to the thin film of close-packed quantum dots.
