Abstract
We studied the effects of surface passivation on the growth of CdSe quantum dots (QDs). In addition, we fabricated QD thin films and light-emitting diodes (LEDs). A chemical colloidal method was used to grow CdSe QDs and their characteristics were evaluated by using a photoluminescence (PL) measurement. An effective surface passivation of mono-disperse CdSe QDs was achieved by overcoating them with ZnS. Layer-by-layer assembly was used to fabricate QD thin films with molecular order and stability. The PL spectra of the QD thin films indicate that the QDs were successfully assembled into thin film. Finally, we obtained electroluminescence images from the active layer of the QD-LED as a function of the injection current.
