Abstract

Arc discharge in liquid helium is a promising method for fabricating high-quality carbon nanomaterials. Measurements of the discharge characteristics of the resulting plasma and observation of the associated optical emission spectra show that the behaviour of discharge current over time and the associated spectra depend strongly on discharge voltage and both may be related to the temperature of the carbon target.
