Abstract

Techniques described herein generally relate to methods of manufacturing devices and devices including a filament having therein or coated with a catalyst and carbon nanotubes. The device may be configured to produce light with a luminary characteristic having a value higher than a value of the luminary characteristic of a device having an uncoated filament at a same operating condition. The luminary characteristic may include one or more of device irradiance or light efficiency. The filament may be a tungsten filament, and the carbon nanotubes may include multiwall carbon nanotubes or single wall carbon nanotubes. The filament may be coated with the carbon nanotubes using one or more deposition techniques including electric arc discharge, laser ablation and chemical vapor deposition (CVD). The filament may be coated with the catalyst using a method including one or more of electroless plating, electroplating, dip coating, spin coating, and radio frequency (RF) sputtering.
