Carbon nitride nanotips were prepared on silicon substrate in plasma-enhanced hot filament chemical vapor deposition system
in which methane
hydrogen and nitrogen were used as the reaction gases. The carbon nitride nanotips were characterized by scanning electron microscopy and micro-Raman spectroscopy. The photoluminescence of the carbon nitride nanotips was measured at room temperature and the photoluminescence spectrum shows two emission bands at 406 and 506 nm. Combined with the Raman spectrum
the microstructure of the carbon nitride was analyzed. According to the structure and photoluminescence mechanism of amorphous carbon nitride films
the photoluminescence of carbon nitride nanotips was studied.
