Thanks in advance! Why binding energy for Mo 3d and S 2p increase by ~0.12eV after Ag nanoparticles deposition on MoS2?

I have deposited Ag nanoparticle on exfoliated MoS2 by using electron beam evaporation method. And the results are as below; Before the Ag nanoparticle deposition, the binding energies are such...

Thanks in advance! I have Ag@MoS2 heterostructure, can someone explain why S2s peak inXPS spectrum redshifted and broadened after the sample is aged?

Ag nano particles are deposited by electron beam evaporation method on mechanically exfoliated MoS2. And XPS data were taken freshly after Ag deposition and after long exposure to ambient atmosphere.

Dear Peter Kapusta, the graph I posted here hasn't been processed, It is actually pristine as it is produced by the LabSpec software after conducting the experiment. May be I don't understand the working mechanism of the software.

Dear Tuhin Khan, you've pointed out something crucial. But I still don't know where to perform autozero/ setzero. Is it in the LabSpec software or is it in the data manipulating software like Origin?
