Abstract We show that in a carbon–helium high-frequency (66 kHz) arc discharge the fullerene yield and composition can be controlled by changing the helium pressure. By emission spectroscopy we could derive the excitation temperature within the arc. We found that the radial temperature gradient of the arc plasma increases with increasing pressure. We further found that with increasing pressure the yield of fullerenes reaches a maximum of 12.6 wt.% at 0.12 MPa pressure and in the range from 0.16… CONTINUE READING
