Reports on Electron Spectroscopy from University of Namur Provide New Insights

June 3, 2014

By a News Reporter-Staff News Editor at Journal of Technology -- Fresh data on Electron Spectroscopy are presented in a new report. According to news originating from Namur, Belgium, by VerticalNews correspondents, research stated, "We report on the application of high resolution X-ray photoelectron spectroscopy (HR-XPS) to provide a fast identification of the size distribution of metal nanoparticles (NPs) embedded in a polymer matrix. An accurate spectral analysis was performed on the metal photoelectron core level to determine the specific calibration curve which relates the metal NP core level binding energy shift to its size, which was independently measured by transmission electron microscopy."

Our news journalists obtained a quote from the research from the University of Namur, "We have fully characterized the binding energy shifts in the case of silver NPs on a polythiophene based polymer layer. This work shows how this procedure can be applied to characterize multimodal size distributions of metal NPs on a statistical adequate sample area, without having typical experimental limitations of a TEM experiment."

According to the news editors, the research concluded: "Moreover, this technique can give access to chemical analysis and by alternating ion beam sputtering and XPS analysis, the NP diffusion along the growth direction can be revealed."
