摘要

采用磁控溅射沉积技术结合旋涂与热处理法,制备了有序Au/TiO₂纳米复合结构阵列。探讨了TiO₂前驱液浓度、Au薄膜沉积厚度、热处理温度对Au/TiO₂纳米复合结构阵列微观结构和物理特性的影响。利用扫描电子显微镜(SEM)分析样品表面微观形貌、紫外-可见分光光度计分析样品表面等离子体共振(SPR)峰与周期性衍射峰变化、接触角测定仪测试样品表面润湿性。结果表明:当前驱液中C₁₆H₃₆O₄Ti与C₂H₅OH摩尔比为1∶100、Au膜沉积时间为100s、热处理温度为800℃时所构筑的Au/TiO₂纳米复合结构阵列形貌最佳,且具有显著的紫外吸收峰以及良好的亲水性。

Abstract

In this work,an ordered Au/TiO₂ nanocomposite arrays were successfully fabricated using magnetron sputtering technology combined with spin-coating and thermal treatment methods.The effects of TiO₂ precursor solution concentration,Au film deposition thickness,and annealing temperature on the microstructure and physical properties of the Au/TiO₂ nanocomposite arrays were investigated.Scanning electron microscopy (SEM) was employed to explore the surface morphology of the samples,a UV-Vis spectrophotometer was used to examine the variation in the surface plasmon resonance (SPR) peak and periodic diffraction peaks,and a contact angle goniometer was used to measure the surface wettability.The results indicated that when the molar ratio of C₁₆H₃₆O₄Ti to C₂H₅OH in the precursor solution was 1∶100,the Au film deposition time was 100 s,and the annealing temperature was 800℃,the Au/TiO₂ nanocomposite array exhibited the best morphology,with a strong UV absorption peak and good hydrophilicity.
