Abstract

With the hydrothermal method, the p-type silicon <100> wafer was used as the substrate to synthesize ZnO nanorods in different synthesis times. To prepare the ZnO seed layer on the p-type silicon <100> wafer, a prepared ZnO gel was deposited as the seed layer using the spin coating method. A 0.2 M solution of zinc acetate dihydrate (Zn(CH3COO)2-2H2O) and hexamethylenetetramine ((CH2)6N4) were used as the source materials at a synthesis temperature of 90 °C. The synthesis time was changed from 10 to 60 min as the synthesis parameter. X-ray diffraction patterns, scanning electron microscopy, and a focused ion beam system were used to analyze and compare the crystal characteristics and the heights and widths of synthesized ZnO nanorods. We found that the crystal characteristics, the heights and widths, and the photoluminescence properties of synthesized ZnO nanorods were dependent on the synthesis time.
合成时间对ZnO纳米棒合成及光致发光性能的影响
采用水热法,以p型硅片为衬底,在不同的合成时间合成ZnO纳米棒。为了在p型硅片上制备ZnO种子层,采用自旋镀膜法沉积制备好的ZnO凝胶作为种子层。以0.2 M二水合乙酸锌(Zn(CH3COO)2-2H2O)和六亚甲基四胺((CH2)6N4)溶液为原料,合成温度为90℃。将合成时间由10 min改为60 min作为合成参数。利用x射线衍射图、扫描电子显微镜和聚焦离子束系统分析和比较了合成ZnO纳米棒的晶体特性和高度、宽度。我们发现合成的ZnO纳米棒的晶体特性、高度和宽度以及光致发光性能都与合成时间有关。
