Abstract
Tetrapod ZnO nanostructures with three different morphologies (rod–wire junction, dumbbell-like (shown in graphic content) and cone-like) and high aspect ratios were synthesized by a vapor oxidation method. They exhibit a strong UV emission (about 380
nm) and three broad green emission peaks, showing good photoluminescent application potential.
Tetrapod ZnO nanostructures with three different morphologies (rod–wire junction, dumbbell-like and cone-like) and high aspect ratios were synthesized by a vapor oxidation method. It was found that these tetrapod ZnO nanostructures had a single crystal hexagonal wurtzite structure with lattice constants of
a
=
0.325
nm and
c
=
0.521
nm. Photoluminescence characterization of such ZnO nanostructures shows that they exhibit a strong UV emission (about 380
nm) and three broad green emission peaks, showing good potential for photoluminescent application.
