GaSxSe1−x solid solutions are layered semiconductors with a band gap between 2.0 and 2.6 eV. Their single crystals formed by planar packings of S/Se-Ga-Ga-S/Se type, weak polarization bonds them, which allows obtaining, splitting, plan-parallel lamellae atomically smooth surfaces. By heat treatment in normal or water vapor-enriched atmosphere, their plates covered layer consisting β–Ga2O3 nanow...

Fluorescence microscopy critically relies on properties of the probes, such as their photoluminescence, biocompatibility and cost. Herein, we report on a newly discovered photoluminescent probe known as nanoruby, which exhibits high quantum yield, extreme photostability, narrow emission spectra and long emission lifetime [1]. These properties make nanorubies suitable for long-term single molecu...
