摘要/Abstract

摘要： 以CdCl₂·2.5H₂O为镉源,TeO₂为碲源,水合肼为还原剂,利用共沉淀-还原法制备了CdTe纳米颗粒。采用扫描电镜、X射线衍射仪、激光拉曼光谱仪、傅里叶红外光谱仪和固体紫外-可见分光光度计对CdTe纳米颗粒的形貌、结构和光吸收性能进行表征。结果表明,水浴温度为80 ℃、水浴时间为6 h、烧结温度为400 ℃、烧结时间为2 h时制备的CdTe有较高的结晶度和较好的光吸收性。通过荧光光谱测试发现,CdTe溶液的荧光强度随谷胱甘肽(GSH)浓度的增加而增大,在0.005~0.8 mmol/L检测范围的检测极限(LOD)为0.004 mmol/L。该研究为制备CdTe荧光探测器提供了新技术,而且为解释GSH在CdTe溶液中的荧光响应提供了依据。

Abstract: CdTe nanoparticles were prepared by co-precipitation reduction method with CdCl₂·2.5H₂O as cadmium source, TeO₂ as tellurium source and hydrazine hydrate as reducing agent. The morphology, structure and optical absorption properties of CdTe nanoparticles were characterized by scanning electron microscopy, X-ray diffractometer, Raman spectrometer, Fourier infrared spectrometer and solid ultraviolet-visible spectrometer. The results show that the CdTe prepared at water bath temperature of 80 ℃, water bath time of 6 h, sintering temperature of 400 ℃, sintering time of 2 h has high crystallinity and good light absorption. The fluorescence spectra show that the fluorescence intensity of CdTe solution increases with the increase of glutathione (GSH) concentration, and the detection limit (LOD) is 0.004 mmol/L in the range of 0.005~0.8 mmol/L. This study provides a new technology for the preparation of CdTe fluorescence detector and a theoretical basis for explaining the fluorescence response of GSH in CdTe solution.
