    摘要:

    首次通過磁控濺射制備了對齊的Au-TiO2納米棒陣列，Au-TiO2納米棒的制備通過直流反應(yīng)磁控濺射法在室溫中進(jìn)行，之后在500oC的空氣中熱處理兩小時，熱處理導(dǎo)致Au-TiO2納米棒的Au納米粒子嵌入到銳鈦礦相TiO2納米棒中, 與傳統(tǒng)方法制備的純TiO2納米棒相比, 這些Au-TiO2納米棒表現(xiàn)出較低的光致發(fā)光強(qiáng)度和較高的光吸收性, 并且對可見光反應(yīng)強(qiáng)烈. TiO2納米棒中的Au納米顆粒能夠抑制電荷復(fù)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.
