| Abstract: | Carbon cones were grown on silicon substrates by bias-enhanced chemical vapor deposition using methane, hydrogen and ammonia as the reaction gases, and the silicon substrates were pre-deposited with titanium and carbon films, respectively. The cones were characterized by scanning electron microscopy, energy dispersive X-ray and micro-Raman spectroscopy. The results indicate that the cones are CN structure. The photoluminescence of CN cones was investigated by micro-Raman spectroscopy at room temperature and the photoluminescence spectrum showed three emission bands centered at about 621,643,726 nm, respectively. According to the photoluminescence mechanism of CN films, the photoluminescence of CN cones was analyzed. |
