摘要：

Raman spectra of boron carbonitride(BCN) nanotubes made by thermal decomposition under different temperatures and with different catalysts were analysized. The intensity ratio of D to G band, I-D/I-G , increases and then decreases with the increase of the temperature. It was indicated that there exists an optimal temperature under which B and N incorporation is maximum. The catalysts influence also the Raman spectra of the BCN nanotubes. I-D/I-G is higher with cobalt/ferrocene and nickel/ferrocene than with cobalt, nickel and cobalt/nickel as catalysts. This means that better BCN nanotubes with B and N contents can be produced with the former. The results were confirmed by TEM observation.
