中文摘要：

采用低温增压晶化法制备了掺杂型纳米晶TiO2。首先采用溶胶-凝胶法制备了4种不同成分的TiO2胶体（TiO2、TiO2＋Zn、TiO2＋Sn和TiO2＋Zn＋Sn）,然后加入双氧水并迅速密封于耐压反应釜中,在100℃温度下反应后得到了掺杂型纳米晶TiO2。采用X射线衍射（XRD）、扫描电镜（SEM）、紫外可见光谱（UV-vis）、光致发光谱（PL）等对制备的样品进行了表征。将制备的纳米晶TiO2组装成染料敏化太阳能电池,测试了电池性能测试,并对性能差异进行了分析。

英文摘要：

TiO2 nano-crystalline with dopant had been obtained at low temperature and high pressure.Four different sols（TiO2,TiO2＋Zn,TiO2＋Sn and TiO2＋Zn＋Sn） were prepared by sol-gel method,then the H2O2 was added and all was sealed in reactor.The temperature was kept at 100 ℃ and the nano-crystalline were obtained.The products were characterized by X-ray diffraction,SEM,UV-vis and photoluminescence spectroscopy.In addition,the Dye-sensitized solar cells（DSSCs） were fabricated by the nano-crystalline,and the cell performance was tested and discussed.
