Abstract

In this paper we report the growth of ZnO nanowires (12-60 nm) and nanorods (500 nm) by a method of Catalysis Free Direct Vapor Phase (DVP) technique. The nanowires were grown on c-Al2O3 and pulsed laser deposited ZnO nucleation layer on Al2O3 substrates at 800 °C without employing any metal catalysts that are conventionally used in MOCVD or Vapor-Liquid-Solid phase techniques. The ZnO nanowires are found to emit UV light at 386 nm with considerably lower green band emission.
