Light emission and excitonic effect of boron nitride nanotubes observed by photoluminescent spectra

Chen, Hua; Chen, Ying; Liu, Yun; Xu, Chao-Nan; Williams, James

Description

Photoluminescent (PL) and optical absorption spectra of high-yield multi-wall BN nanotubes (BNNTs) were systematically investigated at room temperature in comparison with commercial hexagonal BN (h-BN) powder. The direct band gap of the BNNTs was determined to be 5.75 eV, just slightly narrower than that of h-BN powder (5.82 eV). Two Frenkel excitons with the binding energy of 1.27 and 1.35 eV were also determined. However, they were not a distinctive characteristic of the BNNTs as reported...[Show more]
