wo-dimensional ZnO nanosheet networks composed of many thin and uniform hexagonal-shaped ZnO nanosheets and ZnO nanodiscs were prepared in a large scale on silicon substrate through thermal evaporation using ZnCl2 and O2 as source materials for Zn and oxygen, respectively, without the use of metal catalysts or additives. Detailed structural studies indicated that the synthesized products are single crystalline with wurtzite hexagonal structure. Raman scattering of the synthesized products confirmed that the as-grown structures have good crystal quality with a hexagonal wurtzite phase. Room temperature photoluminescence spectra showed a strong green band with a suppressed UV emission from the ZnO nanosheet networks, but on the other hand a dominant and strong near band edge emission with a much suppressed deep level emission was observed in the nanodiscs. The growth mechanism of these structures is also discussed in detail. |

two-dimensional ZnO nanosheet networks composed of many thin and uniform hexagonal-shaped ZnO nanosheets and ZnO nanodiscs were prepared in a large scale on silicon substrate through thermal evaporation using ZnCl2 and O2 as source materials for Zn and oxygen, respectively, without the use of metal catalysts or additives. Detailed structural studies indicated that the synthesized products are single crystalline with wurtzite hexagonal structure. 以氯化锌以及氧气为产物中锌以及氧的原料，通过热蒸法在硅基板上面成功制备了由很多薄的均一的六方形ZnO纳米片以及纳米盘状组成的二维纳米片状ZnO，制备过程中没有使用任何催化剂或者添加剂。进一步的结构研究表明合成的产物为六方纤锌矿单晶。 Raman scattering of the synthesized products confirmed that the as-grown structures have good crystal quality with a hexagonal wurtzite phase. Room temperature photoluminescence spectra showed a strong green band with a suppressed UV emission from the ZnO nanosheet networks, but on the other hand a dominant and strong near band edge emission with a much suppressed deep level eission was observed in the nanodiscs. The growth mechanism of these structures is also discussed in detail. 产物的拉曼测试进一步证实合成的结构具有良好的六方纤锌矿结晶性。室温的光致发光图谱表明产物有一个强的绿色谱带，一个较弱的从ZnO纳米片网状结构处发出的紫外谱，同时在纳米盘结构上发现了一个强度高的近带边发射谱的主峰以及一个较弱的deep level eission。同时在论文中详细讨论了这些结构的生长机理。 deep level eission这个专业词汇不知道其具体意思，仅供楼主参考。  |
