摘要

本研究利用化學水浴法(Chemical Bath Deposition； CBD)進行可見光光觸媒薄膜之製備，以ITO(Indium–Tin-Oxide)導電玻璃為基材，利用此種製程於基材表面先形成一層AgInS光觸媒薄膜，再利用氯化銅進行銅金屬摻雜。而本研究著重於提升半導體薄膜的光敏化效果，試著改變反應溶液pH值與反應時間之鍍膜參數，並將試片置於真空管狀爐中以300 oC燒結1小時。材料分析部分以X-ray繞射儀(XRD)判別薄膜的晶型結構，利用掃描式電子顯微鏡(SEM)來觀察薄膜表面形貌與元素之半定量分析；並利用電化學量測儀以三極式之方式量測光電流，探討光觸媒的成分組成對光電流之影響。
