Abstract

We reported the aqueous chemical method to fabricate the well-aligned ZnO/Al₂O₃ core-shell nanorod arrays (NRAs). The shell is composed of α-Al₂O₃ nanocrystals in amorphous Al₂O₃ layers. The photo luminescence (PL) measurements showed that the enhancement of near-band-edge emission in ZnO NRAs arrays due to the addition of Al₂O₃ shell was observed. The Al ₂O₃ shell layer resulting in flatband effect near ZnO surface leads to a stronger overlap of the wavefunctions of electrons and holes in the ZnO core, further enhancing the NBE emission.
