Abstract

Incandescent bulb filaments, consisting of carbon nanotube (CNT) coated carbon fiber (CNTCF), were fabricated and their incandescent properties were studied. For comparison, carbon fiber (CF) and tungsten filaments were also studied under similar conditions. CNTCF filament of 10 Ω resistance exhibits an illuminance enhanced by a factor of ~400 as compared to tungsten filament of 17 Ω resistance for an applied voltage of 18 V. At an input power of 70 W, CNTCF exhibits an enhancement by a factor of ~3.6 in the illuminance as compared to CF filament.
