我们提出了一种新的通用方法来合成纳米结构的金属（II）氧化物薄膜的衬底上，如硅。真空紫外（VUV）准分子灯使金属有机前体破裂，产生挥发性有机碎片，而表面的金属物质形成氧化物。X射线光电子能谱（XPS）和X射线吸收光谱（XAS）证实，锰和铜酞菁172 nm的真空紫外照射产生锰（II）和铜（II）的氧化物，分别。前体膜的形态提供了形成金属氧化物纳米颗粒的模板，我们证明了尺寸为40 x 40 x 10 nm的颗粒（3）。我们的过程既简单又灵活，具有低热预算和图案化潜力。
We present a new generic method to synthesize nanostructured metal(II) oxide films on a substrate such as silicon. Vacuum ultraviolet (VUV) excimer lamps rupture metal organic precursors, creating volatile organic fragments, while the metal species at the surface form oxides. X-ray photoemission spectroscopy (XPS) and X-ray absorption spectroscopy (XAS) confirm that 172 nm VUV irradiation of manganese and copper phthalocyanines yields manganese(II) and copper(II) oxides, respectively. The morphology of the precursor film provides a template from which metal oxide nanoparticles are formed, which we demonstrate for particles with dimensions 40 x 40 x 10 nm(3). Our procedure is both simple and flexible, with low thermal budget and potential for patterning.
