氧化鋅納米棒制備 已有2人參與

問一個問題,文獻中說使用基板晶種生長法制備氧化鋅納米棒的時候,在基板浸入生長液90℃生長的時候要求基板懸浮在生長液中,這怎么水平懸浮啊 用什么方法能使基板懸浮呢 |

例如Synthesis of ZnO NW films. A typical procedure for synthesizing the ZnO NW films is carried out as in the literature [29]. Firstly, a seed layer was deposited on the conductive F-doped SnO2 (FTO) glass by sol–gel method using the zinc acetate dihydrate (Zn(Ac)2·2H2O, 0.5 mol L−1) as the precursor and then the substrates coated with ZnO seed layer were calcined at 500 ◦C for 1 h. The precursor aqueous solution for the growth of ZnO NW was prepared in advance by mixing the hexamethylenetetramine (HMT, 0.025 mol L−1) and Zn(Ac)2·2H2O (0.025 mol L−1) in deionized water, and stirring for 20 min at 0 ◦C. Then the FTO substrates with ZnO seed layer were immersed into this solution immediately and sealed in a flask in an oven at 95 ◦C for 7 h. Then the films were rinsed in deionized water thoroughly and subsequently heated at 500 ◦C for 1 h. The film obtained in this step was marked as ZNW。Journal of Photochemistry and Photobiology A: Chemistry 219 (2011) 132–138。第一步就是晶種 |
