This paper reports the effect of hydrogen ( H 2) plasma treatment on field emission property of double walled carbon nanotubes (DWCNTs) synthesized by using chemical vapor deposition method. The hydrogen plasma treatment was carried out for various duration. The DWCNTs films were characterized by using scanning electron microscopy (SEM), transmission electron microscopy (TEM) and Raman spectroscopy. The results showed that the field emission properties of DWCNTs were influenced with increasing plasma treatment duration. The Raman spectra of samples clearly show structural defects after hydrogen plasma treatment. It is observed that the change in the field emission characteristics of DWCNTs is attributed to the structural defects due to the H 2 plasma and depends on the plasma treatment duration.
