Potassium Tungsten Bronze Nanowires: Polarized Micro‐Raman Scattering of Individual Nanowires and Electron Field Emission from Nanowire Films

Potassium tungsten bronze nanowires have been successfully fabricated by the hot-plate technique. Polarized micro-Raman scattering studies on the individual nanowires demonstrate single-crystalline properties. Such tungsten bronze nanowire films exhibit impressive electron field emission properties. It is believed that with further improvements potassium tungsten bronze nanostructures could be one of the potential candidates for use in future field emission electron sources and displays (FEDs).
