Zusammenfassung:Zirconium oxide ($ZrO_2$) nano porous membranes were fabricated by electrochemical two-step anodization with an electropolished zirconium substrate in inorganic water-based and organic electrolyte systems containing small amounts of fluoride. Using two-step anodization and organic electrolytes, highly regular and ordered nanotubular $ZrO_2$ oxide layers can be compared with aqueous electrolytes. The morphology and size of the nano porous layers were characterized by FE-SEM (field emission scanning electron microscopy), XRD (X-ray diffraction), and EDS (energy dispersive spectroscopy). Luminescence properties were investigated by photoluminescence measurements. 전해연마를 한 지르코늄(Zr)을 가지고 $F^-$ 이온이 함유된 무기 전해질과 유기 전해질에서 2 단계 양극산화를 진행하여 산화 지르코늄($ZrO_2$) 나노 다공성 산화막을 제조하였다. 2 단계 양극산화를 진행하면서 무기 전해질에서보다 유기 전해질에서 만들어진 지르코늄 산화막이 보다 균일한 나노 다공성 산화막을 가지게 되었다. 나노 다공성 산화막의 크기와 구조는 FE-SEM(field emission scanning electron microscopy), XRD(X-ray diffraction), EDS(energy dispersive spectroscopy)를 이용하여 특성을 분석하였고 형광스펙트럼을 측정하여 $ZrO_2$ 나노 다공성 산화막의 형광성을 알아보았다.
