| 摘 要： | 采用sol-gel法制备TiO2薄膜。用XRD、AFM对其结构及表面形态进行了表征。用UV、SPS测试其光谱吸收、表面光伏特性。结果表明，在高软化温度ITO玻璃上得到比较好的锐钛矿型TiO2薄膜，且具有很强的紫外光吸收特性。随着烧结温度的升高，锐钛矿晶型更加趋于完整，使得紫外吸收曲线的带边蓝移。在紫外光照射下，所制得的薄膜有明显的光伏效应。较之粉体材料，吸收峰更趋向紫外区。为进一步研制新型紫外光传感器提供实验依据。

| Abstract: | Anatase TiO_2 nanocrystal thin films deposited on ITO glass substrate were prepared by sol-gel method. The films were characterized by X-ray diffraction (XRD),ultraviolet spectrophotometer (UV),atomic force microscope (AFM) and surface photovoltaic spectrometry (SPS).The films shows strong ability of UV adsorption and photoconduction, the ability will stronger along with rise of temperature. Wavelength of light the films adsorbed shorter than which powder nanocrystal TiO_2 adsorbed. For researching the new type UV sensor provides the experiment basis. |
