  5. ( 3 ) the free - standing porous silicon films with continuous porous structure were prepared on single crystal silicon wafer by the method of anodic oxidation and electrochemical etching - electropolishing, and firstly used as the anode materials for lithium ion secondary batteries. the capacities of lithium ions storage and the process of charge and discharge of this nano - silicon anode materials as well as the influence of the structure of ps on behavior of storing lithium ions were inspected at length. on the other hand, through the process of charge and discharge in cells, the lithium of light metal element could be electrochemically doped into ps at different doping levels

    胡勁松河北師死大學碩士學位論文( 3 )利用陽極氧化法在單晶硅基底上制備了多孔硅自支撐膜,並首次將這種具有連續多孔結構的硅材料用作了理離子電池的陽極材料,考察了這種納米級硅陽極的儲鉀性能和充放電過程,分析了材料結構對其儲理行為的影響;另一方面,利用這種電池充放電過程在多孔硅中電化學引入了不同點綴程度的輕金屬鉀元素,考察了鉀點綴對多孔硅自身結構,及至性質所帶來的影響,提供了一種通過電化學方法插入埋離子從而連續調整多孔硅發光性質的有效方法。
  6. According to the sample prepared by hydrothermal method, the doping cations can enter the spinel lattice. rare earth cations mostly occupy position b because of their big radius. cerium are oxidized to ce4 +, whose radius is relatively small, and ce4 + mostly occupies position a. as a whole, the coercivity of cobalt ferrite doped with rare earth element is bigger than that of pure cobalt ferrite

    結果表明,對水熱法制備的鐵氧體粒子,雜質離子能夠進入其尖晶石晶格中,並因稀土離子的半徑較大,而絕大部分佔據尖晶石的b位,鈰元素因被氧化成為四價離子,離子半徑相對較小,而主要佔據a位。
  7. It had many great merits such as excellent optical properties, low - cost and easiness to handle which offered promising prospects in the filed of self - cleaning, anti - fog and so on. the hydrophilicity of tio2 was influenced by many factors such as crystal structure, surface morphology, band gap, etc. preparing method and doping element would take effect on the properties of the film

    Tio _ 2薄膜的親水性能受到結構形貌及其禁帶寬度的影響,銳鈦礦相的tio _ 2具有最好的親水特性;平整均勻的表面不僅有利於水的鋪展,而且透光率高,適于玻璃鍍膜;薄膜禁帶寬度降低有利於提高光能的利用率。
