Paper Abstract

ZnO nano-crystals have been paid a great attention as building blocks for the optoelectronic devices. We have been succeeded in growing ZnO nanostructures, such as vertically-aligned ZnO nanowires and nanowalls, by a newly developed nanoparticle-assisted pulsed-laser deposition (NAPLD) without using any catalyst. Depending on the growth condition a film-wire heterostructured ZnO were synthesized on the c-plane sapphire substrates. The room temperature photoluminescence spectrum of synthesized ZnO nanostructures exhibited a strong intrinsic UV emission and a week defect-related visible emission.
