在室温下，通过离子液体 1-丁基-3-甲基咪唑鎓双（三氟甲基磺酰基）酰胺和 1-乙基-3-甲基咪唑鎓三（五氟乙基）三氟磷酸盐电沉积，通过有序聚苯乙烯（PS）模板制备了三维有序大孔（3DOM）Ge 薄膜。我们讨论了通过简单且廉价的模板辅助电化学途径从两种不同的离子液体获得高质量 3DOM Ge 薄膜的可能性。扫描电子显微镜证实了样品的质量，光学测量表明电化学制备的 3DOM Ge 显示出光子晶体行为。这种材料有可能使 3DOM Ge 适用于电气、光学应用和光子晶体太阳能电池。
Three dimensionally ordered macroporous (3DOM) Ge films have been made via ordered polystyrene (PS) templates by electrodeposition from ionic liquids 1-Butyl-3-methylimidazolium bis (trifluoromethylsulfonyl) amide and 1-Ethyl-3-methylimidazolium tris (pentafluoroethyl) trifluorophosphate at room temperature. We discuss the possibility of obtaining high quality 3DOM Ge films from two different ionic liquids by the simple and inexpensive template-assisted electrochemical pathway. Scanning electron microscopy confirms the quality of the samples, and the optical measurements demonstrate that 3DOM Ge made electrochemically shows photonic crystal behavior. Such a material has the potential to make 3DOM Ge feasible for electrical, optical applications and for photonic crystal solar cells.
