Physical unclonable functions (PUFs) are receiving significant attention with the rise of cryptography and the drive towards creating unique structures for security applications and anti-counterfeiting. Specifically, nanoparticle based PUFs can produ

Polarization has been identified as an important parameter in the generation of micro- and nano-structures during ultrafast laser machining. In this study, deep cavities (500 μm x 500 μm x 100 μm) were machined with a femtosecond laser. The influe

In this paper we discuss the optical response of laser-written plasmonic colours on silver coated via the atomic layer deposition of alumina. These colours are due to nanoparticles distributed on a flat surface and on a surface with periodic topograp

We report the passivation of angle-independent plasmonic colors on bulk silver by atomic layer deposition (ALD) of thin films of aluminum oxide. The colors are rendered by silver nanoparticles produced by laser ablation and redeposition on silver. We

Silver gratings supporting surface plasmons at 532 nm catalyze the formation of light-emitting solid carbon from C O 2 gas, revealing a low-energy C O 2 reduction pathway involving hot electrons. Reversibility and spatial control over the formation o

Nanotexturing of silver substrates with silver (I) oxide, Ag2O, is demonstrated using a one-step laser micro-machining process. Where ablation of the silver substrate took place, a highly textured nanoscale topography is generated. In contrast, a fil

We report the tuning of plasmonic colours on silver by controlling the thickness of alumina films deposited via atomic layer deposition. The colours are observed to shift with increasing alumina film thickness. Colour palettes produced with periodic

We report on the creation of angle-independent colors on silver using closely time-spaced laser bursts. The use of burst mode, compared to traditional non-burst is shown to increase the Chroma (color saturation) by ~50% and to broaden the lightness r
