摘要
量子点具有独特的光学特性,被越来越广泛地应用于生物研究和医学临床等领域。本文采用水相合成法,制备了不同表面修饰CdTe量子点,并运用紫外-可见吸收光谱、荧光发射光谱、X射线衍射(XRD)、X射线光电子能谱(XPS)以及透射电子显微镜(TEM)等,对所合成的量子点进行了表征,并探讨了pH值对量子点制备的影响。
Quantum dots （QDs） had special fluorescence properties and a wide application prospect in biological and medicinal fields. CdTe QDs coated with different surface ligands were prepared using aqueous synthesis method. The structures and optical properties of the obtained CdTe QDs were characterized by UV - vis absorption spectroscopy, photo- luminescence spectroscopy, X- ray diffraction, X- ray photoelectron spectroscopy, and transmission electron micro- scope, etc. The effects of pH value on optical properties of QDs were also investigated.
