In this work was studied the synthesis and characterization of single wall carbon nanotubes (SWCN) with phosphorus incorporation. The nanotubes were produced in two different temperatures (800 and 850 Degrees Celsius), using a powder precursor (solid phase) without liquid dilution. The system used for the synthesis was High Vacuum Chemical Vapor Deposition (HVCVD). The samples were characterized comparing the samples with phosphorus with SWNT synthetized with ethanol. Raman spectroscopy, x-ray photoelectron spectroscopy (XPS) on transmission electron microscopy (TEM) were employed to characterize the samples. The Raman spectroscopy and TEM were employed to confirm the presence of SWNT in the samples. We found evidences that phosphorus were incorporated comparing the Raman spectra with the reference sample. The XPS results showed the presence of phosphorus atoms bonded to carbon atoms which make us conclude that the phosphorus were incorporated to the nanotubes.
