Influence of Sb coated substrates in development of vertical and random oriented ZnO nanostructures for UV LED application using nano particle assisted pulsed laser deposition

Abstract

This research highly focuses towards influence of different paprmaters in development of Sb doped ZnO nanostructures using Nano Particle Assisted Pulsed Laser Deposition by using Sb coated substrate.different types of nanostructures were synthesized with vartion in growth temperature. Nano wires generated from Sb coated silicon substrate posses a sharp UV emission from room temperature PL. vertically aligned ZnO nanowires were grown on different ZnO buffer layer thickness ranging from 100 to 1600 nm. With increase in buffer layer thickness a strong UV emission with improved structural properties are observed, which are highly suitable for optoelectronic device application. © 2012 Springer-Verlag.
