Paper Abstract

This paper describes a new growth method of ZnO nano-rods. Firstly ZnO nanoparticles were synthesized in an oxygen and He background gas by laser ablation. These nanoparticles were used to deposit nano-structured-ZnO thin films. Under an optimized deposition conditions, ZnO nano-roods with a diameter of about 300 nm and 6 μm in length have been synthesized without any catalyst by nanoparticle assisted laser ablation deposition. The laser action was observed in the nano-rods under an optical excitation at 355 nm, indicating a high quality of the crystal.
