I have tried to interpret these SEM spectrographs but not sure of the interpretation. I am working in the area of Nanochemistry and will need an expert input in my interpretation.
To interpret SEM images, it is necessary to know what type of samples they are. From what I can assume, they look like dispersed or aggregated silver particles, and some image shows fibers of a much lighter material, which could be carbon. However, to try to help, you need to know what these samples are.
