| 摘 要： | 本文采用无催化剂直接蒸发高纯Zn粉,在800℃氧气氛条件下,在Si(111)衬底上生长得到以四角状为主的纳米ZnO(T-ZnO)。T-ZnO纳米线每个角约互成110°,长度约为1.5μm,直径100nm左右;Raman分析表明E2(H)普遍存在于各形态的ZnO;光致发光光谱表明,T-ZnO纳米线的光致发光除了与材料性质有关,还与杂质缺陷有关,蓝绿光带是ZnO的缺陷产生的。 |
| 关 键 词： | 纳米氧化锌 四角状 拉曼光谱 荧光光谱 缺陷 |

| Abstract: | Nano zinc oxide were grown on n-Si(111) substrate by directly evaporating high pure zinc powder without employing catalyst at 800°C in oxygen.The nano zinc-oxide were mainly tetrapod.The angles of the symbiotic T-ZnO nanowires were about 110°,the length was 1.5μm and the diameter was 100nm.Raman spectra analysis showed E_2(H) existed in different kinds of zinc oxide;photoluminescence spectroscopy(PL) study was also employed,which indicated PL of zinc oxide related to both material property and defects of impurity,blue and green emission bands were originated from defects in ZnO. |
| Keywords: | Nano znic Oxide Tetrapod Raman spectra photoluminescence spectroscopy defect |
