Problems solved by technology

However, when using this method to prepare metal ion-doped titanium dioxide nano-films, usually pure metal titanium and other dopant metals are used as two or more targets, and sputtering is carried out at a certain heating temperature in an oxygen atmosphere. , such as disclosed in CN1876229A, the sputtering rate of this method is low, the reaction process is unstable, it is difficult to completely oxidize metal Ti, and the doping amount of metal ions is also difficult to accurately control, and the distribution of doped metal ions is uneven. uniform
In addition, there are also ceramic targets made of titanium dioxide and metal-doped oxides to prepare titanium dioxide nano-films, such as disclosed in CN1524977A, this method also makes it difficult to accurately control the doping amount of metal ions, and the doped metal ions Difficult to distribute evenly in titania target and film
Therefore, the wide application of magnetron sputtering technology in the preparation of titanium dioxide nano-films is limited.

Technical field: [0001] The invention relates to a method for preparing a metal ion-doped titanium dioxide target material and the target material obtained therefrom. The target material can be used for preparing a metal ion-doped titanium dioxide nanometer film by a magnetron sputtering method. Background technique: [0002] Among the two common crystal structures of titanium dioxide, the anatase phase has high photocatalytic activity, and the rutile phase has strong ultraviolet absorption ability. After they are prepared into titanium dioxide nano-films, due to the refinement of their grain size, they have special nano-effects such as small size effects, quantum effects, and surface and interface effects of nanomaterials. They are coated on the surface of glass, ceramics and other substrates with moisture-sensitive properties. , Gas sensitivity, photocatalysis, super hydrophilic, high refractive index, high dielectric constant, stable chemical properties and other properti...
