My name is Rasmus, and I'm currently a postdoctoral fellow (funded by the Carlsberg Foundation) in the Nanomaterials Spectroscopy and Imaging group within the Transport at Nanoscale Interfaces Lab at EMPA in Switzerland.
Excited to share our work on quasi-1D chalcohalides — optical gaps from 1.3–2.1 eV and we’ve mapped out their electron-phonon coupling. These materials have some seriously interesting optoelectronic possibilities 🤘

BaZrS₃ lights up!!! 🔥✨☀️
From high-quality single crystals, we show BaZrS₃ is an intrinsically strongly luminescent chalcogenide perovskite. The carrier lifetime is short, the electron–phonon coupling a bit unusual – but it glows bright!
Read it before your neighbour 👉 doi.org/10.1002/adom...
