Title: | Direct printing of micropatterned plasmonic substrates of size-controlled gold nanoparticles by precision photoreduction | Authors: | Zhang, Y Liang, Z Zhang, AP Tam, HY |
Issue Date: | 4-Jan-2021 | Source: | Advanced optical materials, 4 Jan. 2021, v. 9, no. 1, 2001368 | Abstract: | Although the extraordinary optical property of gold nanoparticles (AuNPs) has been known for a long time, the anticipated applications of AuNPs in plasmonically enhanced substrates and photonic microdevices are still under development. In this paper, a method for the direct printing of micrometer-scale patterns of size-controlled AuNPs is presented for plasmonic substrates and microsensor development. Using in-house digital ultraviolet lithography, a precision photoreduction technology is developed for light-controlled growth of AuNPs to create micrometer-scale micropatterns on a titanium dioxide photocatalytic layer. The titanium dioxide thin layer not only enables a photocatalytic reduction process for high-precision printing of size-controlled AuNPs in an additive manner, but also introduces a Fano resonance that can sharpen spectral width of localized surface plasmon resonance peak and increase its peak-to-valley value. This printing technology can be used to cost-effectively fabricate size-scalable micropatterned plasmonic substrates of size-controlled AuNPs and thus offers new opportunities to develop various types of miniature plasmonic devices ranging from plasmonic biochemical sensors to plasmonically enhanced photothermal and photovoltaic microdevices. | Keywords: | Gold nanoparticles Optical printing Plasmonic substrate Precision photoreduction |
