| Research Abstract |
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.
