Dear Ramakrishnan,

I think you need to see atomic peak of Cu, Zn, O and /or other elemental peak. I recommend you to read this below article.

Synthesis of Cu, Zn and Cu/Zn brass alloy nanoparticles from metal amidinate precursors in ionic liquids or propylene carbonate with relevance to methanol synthesis

Best!

Here another reference.

Dear Ramakrishnan

For the elemental analysis, you have to measure the XPS spectra in the regions Zn (1000 to 1100 eV, involving Zn 2P1/2 and Zn 2P3/2), Cu (900 to 1000 eV, involving Cu 2P1/2 and Cu 2P3/2). In addition to that spectra in the carbon and Oxygen binding energy regions are also required for the complete analysis.

Hi,

Use the reference books, Handbook of Photoelectron Spectroscopy or Handbook of casaXPS to understand the plotting procedure, elemental identification, oxidation state and concentration of your material.

Before that, you have to calibrate the binding energy of your spectra with respect to the adventious C 1s feature at 284.6 eV.
