摘要

为了研究tio2薄膜和掺杂zr的tio2薄膜的能带结构和光学性质对其光催化性能的影响，采用电子束枪在玻璃上蒸发制备了tio2薄膜和掺杂zr的tio2薄膜。采用紫外可见光谱法和拉曼光谱仪对tio2薄膜和掺zr tio2薄膜的光学性质和吸收光谱进行了表征。分析结果表明:在773Kare退火温度下得到的锐钛矿相膜主要由TiO2组成，由于掺杂Zr，能带隙减小，350~450nm区域的光学吸收系数增大，吸收带出现红移，TiO2的光催化活性增强。

Optical properties and photocatalytic of Zr-doped TiO_2 films

In order to study the effects of band structure and optical properties of TiO2films and Zr-doped TiO2films to its photocatalytic,TiO2films and Zr-doped TiO2films are prepared by electron beam gun evaporation on glass.The optical properties and absorption spectra of TiO2films and Zr-doped TiO2films are characterized by UV-visible spectrometry and Raman spectrometer.Analysis results show that:the anatase phase films obtained at annealing temperature of 773Kare mainly composed of TiO2,the energy band gap is decreased owing to the doped Zr,the optical absorption coefficients are increased in the region of350~450nm,a red shift of absorption band can be found,the photo catalytic activity of TiO2is enhanced.

期刊介绍： The predecessor of Optical Technology was Optical Technology, which was founded in 1975. At that time, the Fifth Ministry of Machine Building entrusted the School of Optoelectronics of Beijing Institute of Technology to publish the journal, and it was officially approved by the State Administration of Press, Publication, Radio, Film and Television for external distribution. From 1975 to 1979, the magazine was named Optical Technology, a quarterly with 4 issues per year; from 1980 to the present, the magazine is named Optical Technology, a bimonthly with 6 issues per year, published on the 20th of odd months. The publication policy is: to serve the national economic construction, implement the development of the national economy, serve production and scientific research, and implement the publication policy of "letting a hundred flowers bloom and a hundred schools of thought contend".
