Simple Template Assisted Synthesis of ZnO Nanowires and their Photoluminescence Property

Abstract:

Article Preview

Arrays of ZnO nanowires were synthesized within the well distributed pores of AAO template by employing an easy wet chemical method. Nanoporous AAO template was fabricated by electrochemical anodization of aluminium, controlling the anodization parameters. ZnO nanowires were characterized by SEM, XRD and EDS. It was found that the ZnO nanowires/AAO exhibits intense photoluminescence (PL) in the UV and visible regions. The blue emission band (432 nm) of the AAO template was originated from the singly ionized oxygen vacancies. The ZnO nanowires exhibit luminescence in the UV (379 nm) and in visible regions (460 and 510 nm), which can be attributed to the band to band electronic transition and oxygen vacancy related defect centers, respectively.
