gamma-Al2O3 by Ag L-alpha, hard x-ray photoelectron spectroscopy

Abstract

Gamma-alumina (gamma-Al2O3) powder was characterized by hard x-ray photoelectron spectroscopy with an Ag L-alpha (2984.2 eV) excitation source. The sample was fixed to a stainless-steel sample holder with copper double-sided adhesive tape. Survey spectrum, C 1s, O 1s, Al 1s, Al KLL, Al 2s, and Al 2p core levels spectra were acquired.
