Unlocking klockmannite: formation of colloidal quasi-2D CuSe nanocrystals and photo-physical properties arising from crystal anisotropy
Urvi Parekh, Nadiia Didukh, Samira Dabelstein +8
Copper selenide is an exceptional quasi-layered monolithic material that exhibits both semiconducting and metallic properties in adjacent visible and near-infrared (NIR) spectral r…

Long-lived Photoluminescence of Photostable One-dimensional Picoperovskites
Maximilian Tomoscheit, Julian Schröer, Jaskaran Singh Virdee +4
We study one-dimensional metal halide perovskite crystals encapsulated in single-wall nanotubes, so-called picoperovskites, using optical spectroscopy. Polarized micro-photolumines…

Zone-sectored organic crystals with spatially resolved exciton dynamics
Moha Naeimi, Tim Völzer, Regina Lange +4
Among the organic semiconductors, rubrene stands out in terms of hole mobility, luminescence yield and exciton migration distance. A novel type of rubrene microcrystal is prepared…
