Abstract

Nanocombs Nanostructure (ZnO) Optical Properties
ZnO comb-shaped dendrites are synthesized by a vapor transport method. Systematic scanning electron microscopy studies of unique nanocomb-shaped dendrites after periodic heat treatments gives direct evidence of sublimation. The ultraviolet (UV) and visible emission depends strongly on the annealing temperatures and the luminescent efficiency of UV emission is enhanced significantly with each subsequent heat treatment.
