Abstract
The surface chemical binding states of NOx-adsorbed La2xBaxSrCu2O6_??_ were investigated by X-ray photoelectron spectroscopy (XPS) analysis. The chemical shift of Cu2p XPS peak for LaBaSrCu2O6_??_indicated the increasing hole concentrations at the level of 02p with NO and NO2 adsorption. On the other hand, the chemical shift of Cu2p XPS peak for La1. 5Ba0. 5SrCu2O6_??_indicated the decreasing hole concentrations at the level of 02p with NO adsorption. These results suggest that the Ba content affects the NOx gas-sensing properties of the layered-cuprates.
