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.

以氯化鋅以及氧氣為產(chǎn)物中鋅以及氧的原料，通過熱蒸法在硅基板上面成功制備了由很多薄的均一的六方形ZnO納米片以及納米盤狀組成的二維納米片狀ZnO，制備過程中沒有使用任何催化劑或者添加劑。進(jìn)一步的結(jié)構(gòu)研究表明合成的產(chǎn)物為六方纖鋅礦單晶。

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.

產(chǎn)物的拉曼測試進(jìn)一步證實(shí)合成的結(jié)構(gòu)具有良好的六方纖鋅礦結(jié)晶性。室溫的光致發(fā)光圖譜表明產(chǎn)物有一個(gè)強(qiáng)的綠色譜帶，一個(gè)較弱的從ZnO納米片網(wǎng)狀結(jié)構(gòu)處發(fā)出的紫外譜，同時(shí)在納米盤結(jié)構(gòu)上發(fā)現(xiàn)了一個(gè)強(qiáng)度高的近帶邊發(fā)射譜的主峰以及一個(gè)較弱的deep level eission。同時(shí)在論文中詳細(xì)討論了這些結(jié)構(gòu)的生長機(jī)理。

deep level eission這個(gè)專業(yè)詞匯不知道其具體意思，僅供樓主參考。
