Abstract

This paper reports the synthesis and characterization of CdTe system in the ternary surfactant mixture. The quantum dots was prepared by quick injection of tri-n-octylphosphine telluride (TOPTe) into reactor that contains a hot mixed cadmium acetate hydrate, 1-octadecene, n-octadecyl phosphoric acid (ODPA), octadecylamine (ODA) and oleic acid (OA). We found that the surfactant of ODPA, OA and ODA were very important for the enhancement at the Photoluminescence (PL) properties CdTe quantum dots.
