Does size of metal particle always decrease with increasing of capping agent to any amount?

In the preparation of metal nanoparticle the particle size decrease with increasing capping (PVP) agent up to some value, but the size of the particle increase after adding more capping agent....

I analyzed the L2 and L3 edge of AuCu nanoparticles using Au foil as a reference for Au nanoparticle. My Au NP intensity is higher than Au foil. Why?

For L2 and L3 edge analysis of Au from AuCu alloy the intensity of my Au nano-particle is higher than the reference (Au foil) it is a little strange for me. Any one reason out this case? Thanks a lot!
