Study on preparation of functional nanoribbons via solid phase reactions under hydrothermal conditions

由于CDW在较低的温度下运动，蓝色青铜显示出许多有趣的行为，并且被认为是纳米带状晶体时表现出新的性质。然而，到目前为止，几乎不可能获得蓝色青铜纳米带。本研究旨在发展蓝青铜的制备方法。首先，我们开发了一种简便的单相蓝色青铜的制备方法。利用这种方法，我们成功地制备了沿准一维金属导电方向的晶体b轴生长良好的钾蓝青铜K0.3MoO_3纳米带。测量了纳米带的一些性质(纳米带的电导率和磁化率)。此外，我们还成功地制备了铯蓝青铜Cs0.3MoO_3和铯-钾青铜混晶Cs0.3-xKxMoO_3(0&lt；x&lt；0.3)的纳米带，这是熔盐法等常规制备方法无法获得的。

Blue bronzes exhibit numerous interesting behaviors due to the CDW motion at a lower temperature and have been expected to show novel properties when being nanoribbon-like crystals. However, so far it was hardly possible to obtain blue bronze nanoribbons. In this study we aimed at developing preparation methods of them.First we developed a facile preparation method of single phase of blue bronze. Using the method we have succeeded in preparing the potassium blue bronze K0.3MoO3 nanoribbons grown well along the crystal b axis that corresponds to the direction of quasi-1D metallic conduction. Some properties of the nanoribbons (the electrical conductivity and the magnetic susceptibility of nanoribbon ensemble) were measured. Furthermore, we have succeeded in preparing nanoribbons of cesium blue bronze Cs0.3MoO3 and cesium-potassium blue bronze mixed crystals Cs0.3-xKxMoO3 (0<x<0.3) that cannot be obtained by usual preparation techniques such as molten salt methods.
