By XPS it may not be possible, are there any other characterization techniques?
It can be possible by XPS and for other techniques you may do UV-vis analysis. There you can anlyse from the electronic transition occurs between Sn2+ and Sn 4+. Anyway, its better to do XPS analysis and I'm sure you can distinguished these states.
i have XPS spectra can you make difference between the Sn+2 and Sn+4 it will be help full ,
in the above XPS pattern, whether tin is in Sn+2 state or Sn +4 state ?
Dear Vijaykumar
Please draw the particular spectra of Sn. Deconvolution the curve. The B.E. for Sn2+ and Sn4+ is very close. Draw the spectra within 450-500 eV. You will get spectra aroung 285-286 eV and for Sn4+ it will be at 486.4 or 486.6 eV. Your figure shows the survey spectra i.e. the whole spectra.
Dear sir ,(Gobinda Behera and Sebastián Feliu)
Thank you for your suggestions
do you think it will be full of accuracy by plotting the graph in between 450 to 500 eV ?
SnMNN auger spectrum in what way it will help sir?
is it possible by any other techniques ?
Dear Sebastián Feliu
Thank you for the detailed information it was very helpful for me , will go with your suggestions.

Dear Vijaykumar:
I think that Electron Energy-Loss Spectroscopy (EELS) is an appropriate technique to distinguish Sn2+ and Sn4+ unambiguously.
Please read my paper in Physical Review B v.69, 233304 (2004) "Differentiation of tin oxides using electron energy-loss spectroscopy".
Dear Mario Moreno,
Thank you very much for the paper i will go through it if anything i need will message you
