Abstract

Here we report the synthesis of multifunctional Ni-encapsulated boron nitride nanotubes (BNNTs), with average diameter and length measuring similar to 30 run and similar to 25 mu m, by a facile ball-milling-chemical vapor deposition route. The resulting BNNTs exhibit an intense blue emission peaking at similar to 480 nm upon similar to 365 nm excitation, and the time-resolved emission spectroscopy shows a photoluminescence decay lifetime of picoseconds. The SQUID magnetization measurements show an enhanced coercivity of 140 Oe. Obtained collective optical and magnetic properties of BNNT suggest that it could be an exceptional choice for future optomagnetic-based sensor devices, biomedical therapy, and bioimaging applications.
