隨著科技的發展，工業污染日益增加，如何透過使用有機材料來製作兼具性能與環保的元件一直是本實驗室追求的目標。其他文獻中使用絲膠蛋白、柚子皮等有機材料來當作生物模板製作光感測器，其透過生物模板改變材料的表面形貌，改善了原本氧化鋅光感測器所擁有的低響應速率、穩定度低等問題，因此本實驗選擇使用蘋果果膠生物模板作為研究主題。蘋果果膠為天然高分子材料，具有資源豐富且取得容易的特性，除此之外還擁有環境友善、無毒性、可在低溫下操作等優點。
本研究透過簡單低溫製程，以蘋果果膠作為生物模板，搭配水熱法備製出具有良好效能之氧化鋅奈米球紫外光感測器。該元件對於紫外光有著優異的感測能力，光暗電流比率可以達到72000，響應時間最快可以達到2.076 秒，同時具有可重複性與穩定性。本研究透過SEM 分析觀察發現氧化鋅由原本柱狀結構轉變為球狀結構，增加其表面積比;藉由PL 及XPS 分析證實添加蘋果果膠可以降低元件的氧缺陷，增進光電流的產生;XRD 分析顯示本元件生長方向與純氧化鋅相同，皆延著c 軸優選取向生長。透過蘋果果膠作為生物模板，有效提升氧化鋅在紫外光感測的性能，使其成為有機光電元件的潛力發展材料。

With the development of science and technology, industrial pollution is increasing day by day how using organic materials to make components with both performance and environmental protection has always been the goal pursued by our laboratory. Previous reports suggested that organic materials such as sericin and grapefruit peel can be used as bio-template to make zinc oxide (ZnO) photodetectors. The bio-template changes the surface morphology of the materials and improves the low response rate and low stability of the original ZnO photodetectors. Therefore, in this experiment we choose to use apple pectin bio-template as the research topic. Apple pectin is a natural polymer material, which has good supporting properties and is easy to obtain. In addition, it has the advantages of being environmentally friendly, non-toxic, and can operate at low temperature.
In this study, a ZnO nanosphere UV sensor was prepared using apple pectin as biotemplate by hydrothermal method. The device has excellent sensing ability for ultraviolet light. The light-dark current ratio can reach 72000, the fastest response time can reach 2.076s, and it has repeatability and stability at the same time. The scanning electron microscopy (SEM) analysis revealed that zinc oxide changes from the original rod structure to the spherical structure and increase its surface area. Photoluminescence (PL) and X-ray III photoelectron spectroscopy (XPS) analysis confirmed that the addition of apple pectin can reduce the oxygen defect of the device and improve the generation of photocurrent. XRD analysis shows that the growth direction of this element is the same as that of pure zinc oxide, and both are preferably grown along the c-axis. Using apple pectin as a bio-template can effectively improve the performance of zinc oxide in ultraviolet light sensing and make it a potential material, for the development of organic optoelectronic components.
