Abstract
B
-doped
MgO
nanowires were synthesized through impurity-assisted physical evaporation of a mixture of
B
and
MgO
with a small amount of
Ga
2
O
3
. The
B
content in the mixture affectsthe morphology of
MgO
nanowires.
B
-doped
MgO
nanotubes and cubes were formed when
B
-rich mixtures were utilized. Ammonothermal treatment of as-synthesized
B
-doped products resulted in the formation of uniform
BN
coatings adherent to nanowire and nanotube surfaces. Thus a facile
BN
coating method was developed. Finally the growth mechanism of the present
BN
-coated one-dimensional nanostructures was proposed.
