近年來，許多一維和二維的氧化鋅奈米結構受到相當大地關注，做為元件基本組成部分的結構材料其蘊藏潛在的用途被視為新一代電子與光電元件不可或缺的部分。先前的研究報導指出，多種類型組成的奈米結構其元件效能更勝於單一類型的奈米結構。在這篇研究中，我們利用低溫化學浴熱法製備出多樣化性的氧化鋅奈米結構，其中包括:奈米柱、奈米牆、奈米花或是混合結構。
首先，我們開發出具有高密度且均勻之三種形貌的奈米結構:奈米柱、奈米牆和奈米花同時生長於基板上且不需要額外添加活化劑。我們所提出來的方法可以控制奈米花位置，將其控制在由奈米柱與奈米牆所組成的的凹槽之中。
再者，我們利用鋁薄膜當作摻雜來源，發現藉由摻雜不同的含量可以將原先奈米柱的結構轉換成奈米牆結構。此外，所以提出來的方法也可以達到高摻雜含量(9 at%)，相對於一般文獻所提到數值。運用此結構於近紫外光感測器上面，在405波長的發光二極體照射下施加一伏電壓下，其光暗電流比可達99.5倍。
進而，我們採取多層結構 (Al/ZnO/Al/ZnO)當作成長奈米結構的晶種層，得到的結果是垂直於基板雙層奈米結構 (奈米柱與奈米牆)，其中再增加層數後同時間反應下相對奈米柱的長度也隨之增加。此外，此結構運用膽固醇生醫感測器上面可提供更多的面積吸附膽固醇氧化脢，在線性區域: 50–500 mgdl-1，其感測靈敏度: 93.82 μA/mMcm2。
最後，將奈米結構運用在太陽能電池上，利用奈米柱上塗佈PMMA當作抗反射層，其中使用氧化電漿處理製備出不同形貌奈米結構，太陽能電池的效率可以提升到11.57 %。此外也將奈米牆的結構運用當做電子收集層運用在鈣鈦礦太陽能電池上，相對於氧化鋅薄膜而言其奈米牆的效率達13.6%。

In recent years, many zinc oxide (ZnO) nanostructures with one-dimensional (1D) and two-dimensional (2D) morphologies, such as nanorods, nanobelts, nanowalls and nanoflowers, have attracted much attention for their potential use as fundamental building blocks for new generation of electronic and photonic devices. In this study, ZnO nanostructure (including nanorods, nanowall, nanoflower and hybrid nanostructures) were fabricated with chemical bath method at low temperature.
Firstly, we developed a hydrothermal method for the growth of three types of ZnO nanostructures: nanorods, nanowalls and nanoflowers. The structures are produced at high densities with a high degree of uniformity on Al-coated SiO2 substrates without the need for surfactant. The proposed method makes it possible to control the distribution of these structures along the grooves created by altering the growth rate of ZnO nanorods and nanowalls.
Secondly, we report on a means of tuning the morphology of ZnO nanostructure using Al thin film as a doping source. An increase in the thickness of the Al thin film causes the evolution of the morphology from nanorods to nanowalls. We managed to produce AZO nanostructures with higher doping concentrations (9 at%) by using various thicknesses of Al film as a reaction layer. The resulting photosensor was tested using a 405 nm light-emitting diode (LED) at a voltage bias of 1 V across the device, wherein a photocurrent-to-dark-current ratio of 99.5 was observed.
Thirdly, we fabricated an overlapping structure of vertical nanorods and nanowalls using a chemical bath method. The proposed multilayer Al/ZnO/Al/ZnO buffer results in the formation of two types of nanostructure (nanowalls and rods) and also increased the length to which the nanorods grow over time. In addition, a cholesterol biosensor was constructed using these nanostructures as supporting materials for cholesterol oxidase loading. The device achieved sensitivity of 93.82 μA/mMcm2 within a linear-range of 50–500 mgdl-1 .
Final, a hybrid nanostructure comprising ZnO nanorods embedded in polymethylmethacrylate (PMMA) was developed for use as an antireflection (AR) coating. The ZnO nanorod/PMMA structure that underwent O2 plasma treatment for 120s presented the highest efficiency of 11.57 %.
In addition, reports on the fabrication of ZnO nanowalls for use as an electron collecting layer (ECL) in CH3NH3PbI3 perovskite solar cells (PSCs). The proposed ZnO nanowalls achieved a fill factor significantly higher than that of ZnO thin films, which translated into a remarkable improvement in power conversion efficiency, reaching 13.6 % under AM 1.5G illumination.
