1. IR spectrum by force to discover around 393 Nm, the Si with the compound and filmy Ti3+/SiO2 that MTES decorates, the absorption of OH peak intensity is filmier than Ti3+/SiO2 reduce slightly, si, O, the absorption of Si the peak increases apparently, show structure of network of oxygen of compound and filmy silicon is more regular, the film of even and dispersive.
IR光谱发现，MTES修饰的Ti3+/SiO2复合薄膜的Si—OH的吸收峰强度比Ti3+/SiO2薄膜的略减小，Si—O—Si的吸收峰明显增强，表明复合薄膜硅氧网络结构更规则，有利于Ti3+的均匀分散。
