Influence of Au doping concentration on structural and optical properties of ZnO:Au films fabricated through magnetron sputtering
Source abstract
Abstract
Abstract Gold-doped ZnO (ZnO:Au) films were prepared by radio frequency (RF) magnetron sputtering and post-annealing methods. The doping concentration of Au was adjusted by controlling the area of Au wires in the sputtering area of ZnO target. It was found that the as-grown ZnO:Au films had better crystal quality than as-grown ZnO films due to small lattice mismatch between Au and ZnO. The solid solubility of Au in ZnO films was found to be 1.00 at.% for the 350oC-annealed ZnO:Au, and it decreased with the rising annealing temperature. XPS results revealed that Au exited in the ZnO:Au with chemical states of metallic Au and positive univalance Au substituted for Zn (AuZn1+). Au concentration-dependent photoluminescence (PL) quenching was observed for ZnO:Au films. Low-temperature PL measurements and schottky model analysis for ZnO:Au films indicated that AuZn1+ and its associated non-radiative recombination center could cause the PL quenching, moreover, the degree of PL quenching was related to the amount of metallic Au in the films.
