More accurate quantitative measurements (Such as XPS or ICP) are needed with your samples.

Alan F Rawle

Look for silver oxide.

Wenjie Ma

You can do XRD and see whether the main peak shifts, because this may indicate the Ag doing. XPS is more accurate that EDS, and it will be much helpful.

Mahmood H. M.

dear Asma Hayoune ; you can use you can use (a) Elemental analysis (EDS) of the silver doped TiO2 to show the presence of Ti and Ag species; (b) UV-Vis diffuse reflectance spectra (DRS) of Ag-doped TiO2, as in the reference ;

Go for XRD

If the doping is at ppm levels then XRD will not pick it up. XRF stands a good chance. As Vadim is hinting, what is the level of the dopant?

Billy Aprianto

Try XRF better than XRD
