The results: the phase transferring range of TiO2 is between 600-750℃; with the doping of tourmaline, the UV-VIS adsorption spectrum of Nd/TiO2 was basically not affected, and showed a gradual Einstein shift with the increase of calcined temperature between 300-750℃; OH intensity of Nd/TiO2 could be enhanced both in irradiation and in no irradiation when tourmaline was added in it; the doping of 0.6% tourmaline led to the best photocatalytic activity of Nd/TiO2 and the best photocatalytic effect appeared when calcined at 600℃.

结果发现TiO2的相变转化区间在600~750℃范围内；电气石掺入对Nd/TiO2材料的光吸收范围基本没有影响，在300~750℃范围煅烧后，随温度升高UV-VIS图谱有逐渐红移现象；电气石的加入使得Nd/TiO2材料在光照及未光照条件下都起到增强OH强度的作用；在Nd/TiO2材料中掺入0.6%的电气石获得最好的光催化活性，600℃下煅烧光催化效果较优。

According to study on UV-Vis opitical property、qualitative antibacterial experiment 、quantitative antibacterial experiment of anatase nano-TiO_2 and antibacterial powder (adulterated by Ag ion and Ce ion) we turned out that antibacterial powder's diffuse reflection spectrum obviously Einstein shift which makes it can absorb more visible-light. Not only irradiated by UV-light but also irradiated by visible-light antibacterial powder both possess photocatalytic capability, which brought new functions that improve latex's quality.

通过对锐钛型纳米二氧化钛和抗菌粉等光催化纳米材料的UV-Vis光学分析、定性抗菌试验、定量抗菌试验的研究表明，复合掺杂银、铈等稀土离子的锐钛型纳米二氧化钛，其UV-Vis漫反射光谱明显红移，大大加强了它对可见光的吸收能力，因此除了在紫外光为光源的条件下具备光催化能力，在普通光源条件下也具备光催化能力。

The results show that the mean particle size of α-Fe2O3 monolayer is about 58 nm. There are characteristic bands at 568, 482 and 386 cm~(-1) in IR spectrum. The absorption of 375 nm in UV-Vis spectrum is the electron transition of ferric and oxygen atom.

结果表明，α-Fe2O3单层膜是由粒径约为58 nm的粒子排布而成，在568、482和386 cm-1处有特征红外吸收峰，在紫外区375 nm处存在明显的吸收，为Fe-O间的电子跃迁，其吸光度值与膜层数间的较好线性关系说明在一定的速度下挂膜，可以将氧化铁溶胶中的纳米粒子较好地转移到基片上。
