Abstract

Electronic structures and magnetic behaviours of zinc oxide nanorods (ZnO-NRs)decorated with nanocrystalline “Au”-particles (nc-Au)have been studied using different spectroscopies, superconducting quantum interference device-type magnetometer and plane wave pseudopotential density functional theory calculations. The presence of intrinsic defects viz. zinc interstitials (Zn i )and/or oxygen vacancies (V O )are established using different spectroscopies measurements. Ultraviolet photoelectron spectroscopy and valence band photoemission spectroscopy suggests that the valence band density of states of O 2p
