Abstract
We prepared graphitic carbon nanotubes (Au-CPNTs) embedded with gold particles of 5 - 6 nm in diameter. First, poly(p-phenylenevinylene) (PPV) nanotubes containing Au particles were synthesized by chemical vapor deposition polymerization (CVDP) of α,α′-dichloro-p-xylene, which was carbonized at 850 °C. Field emission properties of the Au-CPNTs were found to be excellent revealing a low turn-on electric field (2.1 V / μm) and a high amplification factor (11,500). In contrast, the values for virgin CPNTs were 3.1 V / μm and 4,910, respectively.
