Abstract
The effect of aging on surface stabilized CdSe nanocrystals samples has been studied through UV-vis absorption and PL measurements. The UV-vis absorption showed that the absorption maximum shifted to lower energy and the optical density became stronger with aging time. The PL measurements showed that the luminescence intensity increases with aging. The emissions associated with the band edge and shallower trap shifted to lower energy with aging time, whereas that associated with deep traps does not.
