以TiO 2单晶薄膜为衬底，采用光化学沉积法制备了Ag掺杂和Ag/N共掺杂的TiO 2单晶薄膜。我们还调查了样品的光学和磁性使用各种测量。X射线衍射（XRD）谱图中没有出现与银氧化物有关的衍射峰，表明Ag掺杂的TiO 2单晶薄膜中存在Ag原子。X射线光电子能谱（XPS）表明Ag/N共掺杂TiO 2单晶薄膜中存在Ti 4+和Ag°。结果表明，Ag以Ag颗粒的形式沉积在TiO 2单晶薄膜表面。同时，Ag颗粒的掺杂使TiO 2单晶薄膜的铁磁性较未掺杂的TiO 2单晶薄膜略有增强。Ag/N共掺杂TiO 2单晶薄膜的铁磁性受氧空位和Ag粒子协同作用的影响。
We employ TiO2single-crystal films as a substrate and use a photochemical deposition method to prepare Ag-doped and Ag/N co-doped TiO2single-crystal films. We also investigate the optical and magnetic properties of the samples using various measurements. No diffraction peaks related to silver oxide appear in the X-ray diffraction (XRD) spectra, which implies the existence of Ag atoms in Ag-doped TiO2single-crystal films. X-ray photoelectron spectroscopy (XPS) spectra indicate the existence of Ti4+and Ag° in Ag/N co-doped TiO2single-crystal films. It is found that Ag is deposited on a TiO2single-crystal film surface in the form of Ag particles. Meanwhile, Ag particles can slightly enhance ferromagnetism in Ag-doped TiO2single-crystal films compared with the TiO2single-crystal film sample. Oxygen vacancies and Ag particle synergy influence ferromagnetism in Ag/N co-doped TiO2single-crystal films.
