Nanostructured materials have attracted constantly growing interest due to their fascinating, peculiar characteristics as well as their unique applications complementary to the bulk materials. Among all types of nanostructured materials being investigated as yet, the nanostructured materials made of transitional metal oxides have become the major part in nanotechnology study due to the interesting properties this group of material process. Within numerous transitional metal oxides, the tungsten oxides WOx is believed to be one of the most attractive material for researchers due to their distinctive properties; the utilizations of this material include superconductors, electronchromic devices, sensors and so on. However, over the past few decades, it is impossible to study on WOx nanostructured materials because there are few fabricating methods available for this material though these materials are very interesting. As to the barrier for fabricating the WOx nanostructured materials, the special experimental setups were due to be needed because of the high melting point. The research about the characteristics of the WOx nanostructured materials was rarely made due to these barriers. Therefore, we have to study the way that added the new element to lower the high melting point of the source material. And the introduced element has to remain behind with small amount as much as it does not mar the composition of the WOx nanostructured materials.
In this paper, we introduce the experimental method for simple fabricating WOx nanostructured materials which overcomes these barriers during the thermal process. Moreover, we present the electrical, optical, crystallographic properties of fabricated WOx nanostructured materials. |
