Our new paper shows how we can upconvert light more efficiently in nanostructured devices.

My final PhD project is officially out in Advanced Optical Materials! We use 2D perovskite interlayers in a perovskite/rubrene upconversion system to reduce back-transfer and see some cool power and magnetic field dependent behaviour

What is really contained in phonon spectral lines?
We argue both population decay and dephasing are equally important.
Check out our latest publication to find out why: journals.aps.org/prxenergy/a…

New paper out in @PRX_Energy led by @milosdubajic on extracting phonon lifetimes from spectroscopic linewidth data and the contribution of phase relaxation to spectral broadening.
Check it out!

@unsw has just announced the Green Fellowships, named for our esteemed colleague Prof. Martin A. Green. TLDR: 2 year fellowship for those based outside Australia at academic levels spanning Senior Lecturer to Full Professor. Interested? 👇

While they appear roughly 300 billion times per second, it took us several years and over 30 people from 20 institutions to have a chance to sneak in and take a snapshot of the formation of nanodomains in perovskites.
Now that photo is proudly on the cover of Nature Nano: 1/4

🚨new @NatureNano paper🚨
New work led by @milosdubajic on the A-site significance in the dynamic structure of nanodomains in lead halide perovskites.
Big takeaway: FA has less electronic disorder than MA lending to superior optoelectronic properties

Congratulations to @milosdubajic and the @StranksLab for getting this great piece of work over the line. Worth a read if you are interested in the consequences of dynamic nanodomains in perovskites.

If you are interested in the thermoradiative diode, the "night time solar cell", I highly recommend you check out our latest work where we review the physical process that enable this new class of device!

Happy to finally get this out in Nature Chemistry: we use magnetic fields to shine light on singlet fission. @DMdeClercq1 @JialeF @MJYTayebjee @EkinsNed @LaserMikeN @JonBeves @PalliThordarson @quantschmant @dmhuang @Samders9 @ben_carwithen

With a single leap from tabletop to the microscale, engineers at Stanford have produced the world’s first practical titanium-sapphire laser on a chip, democratizing a once-exclusive technology. @StanfordPhoton1 engineering.stanford.edu/mag…
A long time coming to fruition, but our work on confining and controlling phonons with III-V superlattices has finally been published. onlinelibrary.wiley.com/doi/…

So many people are enjoying the Aurorae, both Northern (Borealis) and Southern (Australis!). But, surely you want to know how amazing the science is? This short🧵is about the atomic origins of the green and red light. 1/10

Ever wondered how the A-site cation affects the local structure of lead halide perovskites and how this local structure in turn influences their macroscopic properties? 🤔 Check out our new preprint. 1
