摘要

采用射频磁控溅射法制备了孔径为360 nm的阳极氧化铝模板，制备了Ga2O3纳米棒阵列。通过扫描电镜和x射线光电子测量分析了表面形貌、元素组成和化学状态。随着溅射时间的增加，纳米棒的高度增加，但在制备的纳米棒阵列中会出现空洞和缺陷等不规则结构。紫外可见光谱表明，纳米棒阵列的平均紫外透过率超过65%。因此，本研究中提出的AAO模板辅助薄膜沉积可以被认为是进一步制造紫外线探测器和气体传感器的潜在方法。

Structural and optical properties of Ga2O3 nanorod arrays sputtered using AAO templates

Ga₂O₃ nanorod arrays were prepared by radio frequency magnetron sputtering through an anodic aluminum oxide template with pore size of 360 nm at room temperature. The surface morphology as well as elemental composition and chemical states were analyzed by scanning electron microscope and X-ray photoelectron measurements. With increasing sputtering time, the nanorod height increases but some irregular structures like voids and defects can be found in the prepared nanorod arrays. The UV–Vis spectra show that the average UV transmittance of the nanorod arrays was beyond 65 %. Hence, the AAO template-assisted thin film deposition presented in this research can be considered as a potential method for further fabrication of UV light detectors and gas sensors.
