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...

I am drawing charts for adsorption isotherms: all R square values are around 1, but there are negative signs in y=c+mx equations.It is normal?

Please let me ask a question. I am drawing charts for adsorption isotherms and we normally use linear . And all R square values are around 1 but there are negative signs in y=c+mx equations for...

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.

I usually see PL intensity less than zero for some regions and it is non intuitive for me. ?

The spectrum attached is obtained from LabRAM HORIBA Raman spectrometer. We can see the photon counts for energy between 1.4 eV and 1.5 eV is less than zero.
