采用微波辐射加热的方法,以亚碲酸钠（Na2TeO3）作碲源,以谷胱甘肽（GSH）作稳定剂,在水相中合成出高质量的CdTe量子点。所合成量子点的发射波长从515～630nm可调,荧光量子产率（PLQYs）最高达95%。利用X射线粉末衍射（XRD）、高分辨透射电镜（HRTEM）、紫外-可见吸收光谱（UV-Vis）和荧光发射光谱（PL）等技术表征产物的物相结构和光学性质。用双光子激发荧光法研究CdTe量子点的双光子吸收性质。用双光子激发荧光成像技术,以发红光的CdTe量子点作为双光子荧光探针成功标记了人肺腺癌细胞（A549）。

GSH-stabilized high-luminescent CdTe quantum do source by microwave irradiation in aqueous phase presented. 630nm and the high quantum yield reaches as high as 95 %. ray diffraction pattern （XRD）, high resolution transmission tion and photoluminescence （PL） spectra. The two-photon a gated using the two-photon excitation fluorescence measur （A549） were labeled using red-emitting GSH-CdTe QDs as a aging technique. ts （QDs） were prepared using Na2TeOa as the Te The emission peak of CdTe QDs ranged from 515The obtained CdTe QDs were characterized by Xelectron microscopy （HRTEM）, UV-Vis absorpbsorption property of GSH-CdTe QDs was investiement. In addition, human lung carcinoma cells fluorescence probe by two-photon fluorescence imaging technique.
