High FE current density from tungsten oxide nanowires

摘要：

To date, eld emitters based on various nanomaterials have been considered for eld emission displays, microwave sources and many more. However, emission property degrading irreversibly in low vacuum or oxygen environment becomes a serious problem because of ion back sputtering, physical etching and so on 1, 2. As field emitters, tungsten oxides have attracted considerable attention owing to their promising physical and chemical properties such as chemically inert, robust and a relatively high melting temperature. In this paper, Quasi-aligned tungsten oxide (W18O49) nanowires were grown from commercially available tungsten powders in a horizontal tube furnace. And field emission (FE) performance of the prepared tungsten oxide was also studied.
