Aluminium (Al) nanoparticles (NPs) over a 1.2-cm 2 -size area are fabricated using nanoporous anodic aluminium oxide as shadow masks. With this technique, plasmon response of Al NP arrays with different out-of-plane height is investigated. The dipolar-localized surface plasmon resonances (LSPRs) peak of Al NP arrays is blueshifted and then redshifted slightly with an increase in particle height…
