| Abstract: | The Cu2O particles or clusters dispersed mesoporous SiO2 composite films were prepared by a new method: First the matrix SiO2 films were prepared by sol-gel process combined with the dip-coating technique, and then they were soaked in Cu(NO3)2 solutions followed by γ-ray irradiation at room temperature and in ambient pressure. Thus prepared Cu2O/SiO2 composite films were examined by X-ray diffraction, transmission electron microscopy, X-ray photoelectron spectroscopy and optical absorption spectroscopy. Compared with the pure Cu2O nanoparticles, an obvious blue shift existed in the obtained Cu2O/SiO2 composite films. |
