In situ measurements were executed in the continuous wave CO 2 ‐laser vaporization synthesis of single‐walled carbon nanotubes (SWCNTs). The results were compared with the findings of the ex situ analysis of the product. Different catalysts (Co, Ni, Co/Ni, Ni/Y and Co/Y) were used and the temperature of the target surface ( T s ) changed to compare the efficiency of the synthesis process. Our main results are related to the SWCNTs diameter which is depending on T s and on the catalysts nature. The targets containing Y with Co or Ni atoms produce more and larger SWCNTs than Co/Ni targets. The SWCNTs' diameter is seen to increase with T s . (© 2006 WILEY‐VCH Verlag GmbH & Co.
