The d-band and the core-level spectra of gold deposited on aluminium and sapphire were investigated utilizing X-ray photoelectron spectroscopy (XPS). For thin deposits of gold, the d-band splitting was observed to be narrowed significantly with respect to that of bulk gold. The narrowing effect is attributed to the high surface to bulk ratio of the gold deposits. A shift of Au 4f core levels also occurs in correlation with the d-band effect.
