Abstract:
Raman spectra of boron carbonitride (BCN) nanotubes made by thermal decomposition under different temperatures and with different catalysts were analyzed. 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.

The monochromatic laser source, typically using visible or near-infrared radiation, generates a highly focused beam of light. This light interacts with the molecules of the sample, scattering some of the light. Liquid and gaseous samples are usually tested in ordinary glass capillaries, while solids can be analyzed as powders packed in capillaries or as potassium...
