Temperature Activated BN Substitution Of SWCNT

Abstract. A promising recipe for the production of single wall boron nitride nanotubes (BNT) is the so-called substitution reaction. We used SWCNT (HiPCo) as a starting material, B2O3 and N2 gas as boron and nitrogen sources respectively. An important complication arises due to the presence of the reacted variants in the final product. We performed optical and multi frequency Raman measurements to identify the phonon modes of BNSWNT and unwanted side-products
