Abstract

Ordered arrays of ZnO nanodots were fabricated by pulsed laser deposition (PLD) using an anodic aluminium oxide (AAO) nanopore membrane. Hexagonal-shaped ZnO nanodots with an average diameter of 60 nm and a periodicity of 100 nm were uniformly assembled into hexagonally ordered nanopores of the AAO membrane. Control of the oxygen pressure used in PLD resulted in a preferential photoluminescence (PL) at 380 nm from the ZnO nanodots: keeping the higher O₂ pressure gave a dominant PL peak in the UV range over the visible range, which is attributed to the reduction of the number of oxygen vacancies.
