研究目的
Investigating the effects of introducing Au into Ag29(LA)12 3 – clusters on their stability, luminescence efficiency, and structural properties.
研究成果
Doping Ag29 clusters with Au enhances their stability and luminescence efficiency, with the Au atom preferentially located in the center of the cluster. XANES is shown to be a valuable tool for structural characterization, requiring less time and lower concentrations than EXAFS.
研究不足
The study is limited by the reproducibility of the synthesis and the sensitivity of the clusters to radiation damage during X-ray absorption spectroscopy.
1：Experimental Design and Method Selection:
The study involved doping Ag29 nanoclusters with Au and characterizing the resulting bimetallic clusters using mass spectrometry, optical spectroscopy, and X-ray absorption spectroscopy.
2：Sample Selection and Data Sources:
Samples with varying Au concentrations were prepared, and their optical properties were analyzed.
3：List of Experimental Equipment and Materials:
UV-Vis spectrometers, spectrofluorometers, mass spectrometry instruments, and X-ray absorption spectroscopy equipment were used.
4：Experimental Procedures and Operational Workflow:
The synthesis of Au-doped Ag clusters, their purification, and subsequent characterization were detailed.
5：Data Analysis Methods:
The data were analyzed using fitting models for mass spectrometry and EXAFS, and first-principles calculations for XANES.
