Upscaling Pulsed Laser Fragmentation in Liquids by Advanced Free‐Flow Setups

Advanced Materials Technologies, EarlyView.
Advanced flow setups providing thin colloid films are introduced to upscale pulsed laser fragmentation in liquids for sustainable nanoparticle synthesis. Their potential is demonstrated by yielding remarkably small ZnO nanoparticles of <7 nm. Numerical simulations complement the study, revealing that the superior performance can be attributed to ...

A Layered Two‐Dimensional Hydrogen‐Bonded Organic Framework Based on 2,5,8,11‐Tetrakis(4‐Carboxyphenyl)Perylene Diimide: Structural Nature, Optical and Photophysical Properties

Advanced Optical Materials, EarlyView.
A novel hydrogen‐bonded organic framework (HOF) based on perylene diimide (PDI) is synthesized, structurally and spectroscopically characterized. Its photophysical behavior highlights how supramolecular organizations govern the optical properties, including emission from monomers, aggregates, and excimer‐like species. Structural transformations induced

Quantum emitters in hexagonal boron nitride

Quantum Nanophotonic Materials, Devices, and Systems 2020, 2020
Hexagonal boron nitride (hBN) has emerged as a fascinating platform to explore quantum emitters and their applications. Beyond being a wide-bandgap material, it is also a van der Waals crystal, enabling direct exfoliation of atomically thin layers─a combination which offers unique advantages over bulk, 3D crystals.
