基于AAO模板的TiO 2 微纳结构及其光电特性
Micro-structure of titanium dioxide(TiO2) layers were prepared by RF sputtering and Sol-gel on conductive glass FTO and porous alumina(AAO).The results show that there are great differences in the two kinds of TiO2.XRD diffraction and Raman scattering spectra illustrate that the crystal structure of TiO2prepared by RF sputtering and Sol-gel are different after being calcinated at500 ℃.On the conductive glass FTO,the TiO2particles prepared by RF are distributed evenly and no cluster phenomenon,but the TiO2prepared by sol-gel consist of small particle.On AAO templet,TiO2sol particles are easy to flow in the hole due to the liquidity colloidal solution,which is contrary with the simple prepared by RF.The photocurrent experiment results show that the TiO2prapered by sol-gel have better photocurrent performance.
