摘要

本文报道了三元表面活性剂混合物中CdTe体系的合成和表征。将三正辛基碲化膦(TOPTe)快速注入到含有醋酸镉水合物、1-十八烯、正十八烷基磷酸(ODPA)、十八胺(ODA)和油酸(OA)的热混合反应器中制备量子点。我们发现表面活性剂ODPA、OA和ODA对增强CdTe量子点的光致发光(PL)性能非常重要。

Enhanced-photoluminescence properties of CdTe quantum dots prepared from the ternary surfactant mixture system

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.
