A new paper from our collaboration with colleagues at TU Chemnitz and Hasselt University is now out in Applied Physics Letters. Circular dichroism spectroscopy is increasingly used to study chiral thin films, but optical anisotropy can introduce linear-dichroism and birefringence contributions that masquerade as genuine chiroptical signals. In this work, we present a practical step-by-step […]

A Nature Nanotechnology paper combines high-resolution electron microscopy and hyperspectral photoluminescence microscopy to investigate unusual low-temperature emitters in FAPbI3.

An ACS Photonics paper shows how resonant-cavity engineering can produce efficient narrowband perovskite photodetectors with tuneable spectral sensitivity.

A Nature Reviews Methods Primers article surveys photoluminescence-microscopy methods, practical considerations, and figures of merit for modern optoelectronic materials and devices.

A Nature Nanotechnology study explains how dynamic local structures of lower symmetry coexist with the average crystal structures measured by X-ray diffraction.

Simon’s ACS Materials Letters Viewpoint examines the pathways, experimental probes, and terminology used to describe broadband luminescence in perovskite-inspired semiconductors.

A Nature Communications paper shows how photonic engineering can control the directionality of photoluminescence and electroluminescence from perovskite LEDs.

A Matter paper led by Xiyu Luo examines heterogeneity in blue perovskite light-emitting diodes.
