研究目的
Investigating the scattering properties of aqueous solutions of CdTe quantum dots with and without gold nanoparticles.
研究成果
The scattering intensity of the aqueous solution of CdTe quantum dots with gold nanoparticles was about 1.5 times greater than that of the solution without gold nanoparticles. This result can be widely used in the medicine field and optical field.
研究不足
The small difference between the simulation and experiment results from the assumption that, in the simulation, the size of gold nanoparticles and CdTe QDs are Gaussian distribution.
1：Experimental Design and Method Selection:
The study used chemical crystal growth method to prepare aqueous solutions of CdTe quantum dots with gold nanoparticles. The scattering properties were simulated using Finite Difference Time Domain (FDTD) method and verified by absorption spectrophotometer.
2：Sample Selection and Data Sources:
Samples were prepared by chemical methods, and their properties were measured using transmission electron microscopy and absorption spectrophotometry.
3：List of Experimental Equipment and Materials:
Equipment included a transmission electron microscope (Tecnai G2 20 S-TWIN), a multifunction detector (Infinite M200 PRO), and a tunable laser (Opolette355LD+UV2M). Materials included chloroauric acid, sodium citrate, CdCl2, and 3-mercaptopropionic acid.
4：Experimental Procedures and Operational Workflow:
The procedure involved preparing gold nanoparticles and CdTe quantum dots separately, then combining them to form the composite solution. The scattering properties were then measured and simulated.
5：Data Analysis Methods:
Data analysis involved comparing the scattering intensities and wavelengths of the solutions with and without gold nanoparticles.
