The targets showed clear XRD peaks of the STO until the doped Co amount reached 30% denoted as Co(30)-STO. Doped Co ions were substituted with octahedrally coordinated Ti ions as the Co2+ state, which was proved by the Co 2p satellite peaks in the X-ray photoelectron spectroscopy (XPS) spectra. The STO and Co(30)-STO targets were treated to evaluate their charge compensation as follows; sputtered by an Ar ion gun, exposed to air, reduction with hydrogen at 1073 K, then exposed to air, and oxidized at 1073 K. Following exposure of the Ar-sputtered target to the air, charge transfer reactions occurred among Co2+,Ti3+,O2- and Sr2+ species which were clarified by their XPS spectra. The origin of two kinds of O 1s spectra detected at 530 and 533 eV was studied by these five treatments and was assigned to the bulk and surface oxygen species, respectively. The PLA of the STO and Co-STO targets was carried out in water at 355 nm and with a constant laser fluence. The atomic ratios of the Ti/Sr and Co/Sr as well as that for the two kinds of O 1s spectra of the LA thin films were studied. The effect of the doped Co ions in the crystal structure of the thin films was studied by the XRD peak shift of the SrTiO3 (110) face. Diffuse reflectance spectra revealed a quantum-sized effect for the r.t. deposited STO thin film, and a d-d transition and charge transfer band for the Co-STO targets. Photo-degradation of methylene blue was carried out on the PLA thin films under very weak power (0.7 mW) visible light at 460 nm from which a quantum yield was obtained to evaluate the role of the doped Co ions in the STO.","subitem_description_type":"Abstract"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Elsevier B.V.
