Synthesis and photoluminescence of tetrapod ZnO nanostructures

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.
