| 摘 要： | Somorjai等曾报道在不同电势下,测得掺MgO氧化铁光电极具有n,p两种类型的光响应。最近本实验室首次报道了在同一电势下,热形成的掺MgO-Fe_2O_3光电极具有n,p型双重光响应共存现象,由于其在电催化等中可能的应用价值引起了较广泛的兴趣。本文对掺入ZnO的Fe_2O_3粉末压片高温烧结法制备的电极的光响应进行了进一步

| Abstract: | Zn-doped iron oxide electrodes that exhibit n-type and p-type photoresponses simultaneously at certain potential interval were prepared. Transformation of n-type photoresponse at more positive potential to p-type photoresponse at more negative potential was showed. The photo-voltage waveforms at different potentials were explicitly measured. It was found that the waveforms at intermediate potentials are linear pile of typical n-type and p-type waveforms. A model based on the existence of multiphase both on the surface and in the bulk of the electrode was advanced. |
