水溶性 MPA-CdSe 量子点的可控合成与荧光性能研究
Controlled Synthesis and Fluorescence Property of Water-soluble MPA-CdSe Quantum Dots
摘要
Abstract
A water-soluble MPA-CdSe quantum dots (QDs)was synthesized using mercaptopropionic acid (MPA)as a stabilizer.The structure,dispersion and morphology of the product were characterized by UV-vis spectra,fluorescence spectra,transmission electron microscopy (TEM)and XRD,respectively.The results showed that the target MPA-CdSe QDs had good dispersion (nano-sized ca.2~3 nm)and excellent fluorescence property,and the quantum yield reached 83% when reaction temperature and reaction time were 1 10 ℃ and 5 h, respectively.关键词
