摘要


本研究目的是利用溶膠凝膠法結合旋轉塗佈技術來製備ZnO:Al(AZO) 薄膜,研究不同的Al參雜濃度和不同的熱處理條件下的AZO 薄膜之 光電性質,並企圖在AZO 薄膜中添加金屬微粒來增進AZO 薄膜的光 電性質。 本實驗以帶結晶水的醋酸鋅為起始材料,添加不同劑量的硝酸鋁作為 摻雜物,再施以不同的熱處理溫度進行退火。AZO 薄膜的電阻率以 含1.5at%Al,在750℃氬氣下退火時,可以得到最低的電阻率,其電 阻率為4.613×10-2Ω–cm。2at%Al-650℃的AZO 溶膠塗怖在含有金屬 微粒的石英玻璃基板上來鍍製成膜,施以同上的溫度在氬氣下退火, 以80秒蒸鍍的金層上鍍鋅鋁氧化物薄膜,可得到最低電阻率為1.289 ×10-3Ω-cm,降低電阻2個order,可見光穿透率為60~70%,降低可見 光率約為25%(無添加Au 微粒的鋅鋁氧化物薄膜電阻率約4.8×10-1Ω -cm,可見光穿透率為90%)。將金膜熱處理得的奈米金,再鍍鋅鋁氧 化物薄膜,可得到最電阻率為4.652×10-2Ω-cm,降低電阻約1個order, 可見光穿透率約70%,降低可見光率約為20%。

The goal of this study is to use sol-gel method and spin coating technique to prepare ZnO:Al (AZO) thin films and to study the influence of Al doping concentration and thermal treatment condition on the electro-optical properties of AZO thin films. Au nano particles were also added in hope to improve the optical-electrical properties of AZO thin film. Zinc acetate dihydrate was used as a starting material in this experiment. By adding different amounts of aluminum nitrate nonahydrate as dopant and annealing in various temperatures, a minimum resistivity of 4.613×10-2Ω-cm was obtained for the films doped with 1.5at% Al and annealing at 750℃ in Ar. A minimum resistivity of 1.289×10-3Ω-cm was obtained for the films which was doped with 2at% Al and contained Au nano particles and annealed at 650℃ in Ar. The incorporation of Au particles decreased two order of the resistivity of AZO thin films and the optical transmittance was also decreased to 50-70%.
