水溶性CdTe量子点制备及光谱性能

Synthesis and Fluorescence Properties of Water-soluble CdTe Quantum Dots

    摘要
  • 摘要: 采用N-乙酰-L-半胱氨酸(NAC)为修饰剂,制备了水溶性的CdTe量子点。实验探讨了酸度、Cd与NAC摩尔比、Cd与Te摩尔比,以及反应时间对CdTe量子点荧光性能的影响。结果表明:当mol(Cd):mol(Te):mol(NAC)为1:0.3:1时,CdTe量子点荧光性能最好。通过测定量子点的紫外吸收光谱得出,随反应时间延长量子点的粒径从2.00 nm增加到3.69 nm。实验还通过红外光谱(IR)和X射线粉末衍射(XRD)对CdTe量子点进行表征,结果表明在CdTe量子点表面成功修饰了NAC。

     

    Abstract: Water-soluble CdTe quantum dots (QDs) were synthesized by using N-acetyl-L-cysteine (NAC) as modifier. The influence of acidity, the molar ratio of Cd:NAC and Cd:Te, and aging time on photoluminescence of obtained QDs had been discussed. The experimental results showed the optimum molar ratio of Cd,Te and NAC was 1:0.3:1. Particle size of QDs increased from 2.00 nm to 3.69 nm along with the extending of reaction time according to UV spectra of QDs. The water-soluble CdTe QDs were further characterized by infrared spectra(IR), and X-ray powder diffraction(XRD), and the experimental results indicated that CdTe was successfully modified by NAC.
