| Abstract: | As the potential applications of carbon nanotubes in the field of electroluminescence,elements yttrium and europium were introduced to modify the emission properties of double-walled carbon nanotubes(DWNTs)to obtain higher efficacy and other properties.The light emission spectrum of the Y-Eu-doped DWNT filament is suppressed in the near-infrared range,while enhanced in the mid-infrared range.The doped DWNT filament can reach higher efficacy than that of the pure DWNT filament at the same input power and can... |
