They are able to absorb a large fraction of visible light, with a reduced thickness. The most adopted structure is a bottom metal mirror, an oxide spacer, and an outer layer of Au nanoparticles, which Daniel Gomez pioneered using vacuum-based depositions: pubs.acs.org/doi/10.1021/acs…
Here we used TiO2 and Au nanocrystals and assembled them into coatings of precise thickness and surface coverage, obtaining structures that when deposited on a mirror, were able to absorb broadly in the visible an near infrared, with a peak absorption of light of 95% at 530 nm.
We present the fabrication of #plasmonic super absorbers using wet chemical methods, and their use as optical gas sensors. Super absorbers are nanostructures based on a mirror-spacer-nanoparticle architecture, and they function through optical interference and field localization.

Copper Tungstate (CuWO4) thin films can split water very effectively under sunlight!
Great work by PhD student Kanishk, and many contributors from within and outside the group!
Check it out! 👀

First, we present a simple synthesis for CuWO4, highlighting the role that water plays in the complexation of ions within the precursor solution. Then we discovered that Cu exhibits unusually high oxidation state (higher than +2), compensated with a reduced tungsten valency.
What a way to wrap up the year! 2 DP EoI submitted yesterday and a research award today! Time to crack open a cold one!

In this work we present a simple, water based method to deposit phase-pure hematite Fe2O3 coatings for water oxidation.
Lead author Triet discovered a strong interplay between dopants and annealing conditions, finding an optimal combination to achieve high performance. 😲
Good luck everyone!

I don't usually like to brag, but this news deserves an exception: I have been promoted to full professor effective 1 January 2025!!! A massive THANK YOU to my group, my colleagues and my collaborators who supported me along the way, and to the reviewers for their endorsement!
Wonderful visit today from former PhD student @Jaewon53624981 . It was great catching up after almost 3 years!

🥳Someone turned 6 today (where did that time go??) and she is pretty excited to work on her new #science project... Big parenting goals here! #birthdaygirl #AcademicTwitter #ozchem #chemistry
