this paper might help. But still, for SERS, it seems very tricky whereas SEM is a straightforward characterization technique.

Thank you!

Hi,

I agree completely wiht Prithu. SEM allows you to see the particles and their distribution and even their size polidispersity, what you could obtain from dark field scattering is probably an average of the are you are studying and it could give you similar values for different configurations of your particles (they can aggregate, in some places... ) There are too many variables that keep out of your control, while with SEM it is straightforward.

Best

You are wellcome!
