| 摘 要： | 首次通过磁控溅射制备了对齐的Au-TiO2纳米棒阵列，Au-TiO2纳米棒的制备通过直流反应磁控溅射法在室温中进行，之后在500oC的空气中热处理两小时，热处理导致Au-TiO2纳米棒的Au纳米粒子嵌入到锐钛矿相TiO2纳米棒中, 与传统方法制备的纯TiO2纳米棒相比, 这些Au-TiO2纳米棒表现出较低的光致发光强度和较高的光吸收性, 并且对可见光反应强烈. TiO2纳米棒中的Au纳米颗粒能够抑制电荷复合

| Abstract: | The growth of well-aligned Au/TiO2 nanorods arrays by magnetron sputtering is presented for the first time. The feasibility of preparing Au/TiO2 nanorods was demonstrate via a dc reactive magnetron sputtering at room temperature and heat-treatment at 500 oC in air for 2 h. The heat treatment leads to the formation of Au/TiO2 nanorods with Au nanoparticles embedded in the TiO2 nanorods of anatase phase.These Au/TiO2 nanorods showed lower photoluminescence emission intensity and higher absorption and intensive response to the visible light, compared with traditional TiO2 nanofilms fabricated by similar method. The Au nanoparticles in the TiO2 nanorods suppress the charge recombination. |
