【摘要】：采用低溫水熱法在摻鋁氧化鋅(AZO)基底上,通過在溶解有乙酸鋅(ZnAc_2)與六次甲基四胺(HMTA)的反應(yīng)溶液中引入NH_4NO_3與In(NO_3)_3,制備出不同形貌和光學(xué)性能的ZnO納米柱陣列。采用掃描電子顯微鏡、透射光譜、光致發(fā)光發(fā)射譜研究了NH_4NO_3與In(NO_3)_3對(duì)ZnO納米柱陣列的結(jié)構(gòu)和光學(xué)性質(zhì)的影響。結(jié)果表明:溶液中添加的In(NO_3)_3顯著地降低了ZnO納米柱的密度,增大了納米柱之間的間距,從而能夠作為太陽能電池的減反射層使用。通過控制NH_4NO_3與In(NO_3)_3在反應(yīng)溶液中的添加比例,可以在3.35~3.62 e V范圍內(nèi)調(diào)控所制備的ZnO納米柱的光學(xué)帶隙寬度。
[Abstract]:In this paper, NH_4NO_3 and In (NO_3) _ 3 were introduced in the solution of the reaction of zinc acetate (ZnAc_2) with hexamethylenetetramine (HMTA) on (AZO) substrate doped with aluminum oxide by low temperature hydrothermal method. ZnO nanoscale arrays with different morphologies and optical properties were prepared. The effects of NH_4NO_3 and In (NO_3) _ 3 on the structure and optical properties of ZnO nanocolumn arrays were investigated by scanning electron microscopy (SEM), transmission spectroscopy and photoluminescence spectroscopy. The results show that the addition of In (NO_3) _ 3 in the solution can significantly reduce the density of the ZnO nanorods and increase the spacing between the nanorods, so it can be used as an antireflective layer for solar cells. By controlling the ratio of NH_4NO_3 to In (NO_3) _ 3 in the reaction solution, the optical band gap width of the prepared ZnO nanocolumn can be controlled in the range of 3.35 ~ 3.62 EV.
