Cathodoluminescence of boron nitride nanotubes doped by ytterbium

Chen, Hua; Chen, Ying; Liu, Yun


Boron nitride nanotubes (BNNTs) are wide band gap semiconducting material with super thermal and chemical stabilities, which make them an ideal nano-sized host for luminescent ions. In this work, we report an in situ synthesis of Ytterbium (Yb) doped BNNTs using a ball milling and annealing approach. Yb doped BNNTs show more red-light emissions in the cathodoluminescent (CL) spectrum in comparison with pure BNNTs. The light emission is due to the insertion of Yb ions into the nanotube wall as...[Show more]
