Abstract The direct laser writing (DLW) of photoluminescent metal clusters is inspiring intensive research in functional glasses. However, understanding the influence of the host structure on cluster formation and visualizing DLW-induced clusters at the atomic scale remains challenging. In this work, we develop a highly photosensitive fluorophosphate glass through fluorine incorporation.

Abstract Silicon is vital for its high abundance, vast production, and perfect compatibility with the well-established CMOS processing industry. Recently, artificially stacked layered 2D structures have gained tremendous attention via fine-tuning properties for electronic devices. This article presents neuromorphic devices based on silicon nanosheets that are chemically exfoliated and surface-modified, enabling self-assembly into hierarchical stacking structures.

The Sb2Se3 is highly interesting narrow band gap semiconductor with promising applications in new-generation electronic and photoelectronic devices. However, it has intrinsically low electrical conductivity which limits its broader scope of applications. To overcome this challenge, the Sn-doped Sb2Se3 ((SnxSb1-x)2Se3) nanorods with enhanced electrical conductivity are firstly synthesized via a facile hot-injection method.
