Abstract
An analysis is given of the electronic structure of Pd nanoparticles
synthesized by inert gas evaporation technique. A study of the effect
of size on various core and valence electrons in Pd nanoparticles
reveals a varied dependence of binding energy of electrons in different
electronic levels. The shift in the Pd x-ray photoelectron spectroscopy
4d valence band centroid is more than the core level shift. The results
of the present study provide a direct evidence of interplay of quantum
confinement (a size effect) and coordination reduction (a surface
effect).
