Paper Title:
Synthesis and Cathodoluminescence Study of Well-Aligned Planar-Tip and Tapered-Tip ZnO Nanorods
  Abstract

Vertically aligned ZnO nanorods have been synthesized on a-plane sapphire via a metal catalyzed vapor phase transport and condensation process in a two-zone vacuum furnace. Planar-tip ZnO nanorods were synthesized using commercial ZnO and graphite powder as the source of Zn vapor controlled by a simple vapor-liquid-solid (VLS) process. On the other hand, tapered-tip ZnO nanorods were synthesized from pure ZnO powder governed by both VLS and vapor-solid processes. From room temperature cathodoluminescence measurements, planar-tip ZnO nanorods are applicable for room temperature UV nanolasers.
