Nanoporous Scaffold‐Assisted Ligand‐Free CsPbBr3 Quantum Dots for Bright and Ultrapure Green Light‐Emitting Diodes

open access: yesAdvanced Optical Materials, EarlyView.
Networks of confined CsPbBr3 perovskite quantum dots, synthesised within nanoporous silica scaffolds using precursors containing different combinations of butylammonium bromide and crown ether additives, enable electroluminescent devices with 400‐fold enhanced charge injection and transport with respect to control devices, yielding ultrapure green ...

Rotating Fluorescent Nanodiamond Assemblies With Focused Laguerre–Gaussian Beams

open access: yesAdvanced Optical Materials, EarlyView.
Self‐assembled fluorescent nanodiamond clusters are optically trapped and driven into controlled two‐dimensional rotation with Laguerre–Gaussian beams. With localized optical excitation, optically detected magnetic resonance spectra are collected at defined points along the orbit in a uniform external magnetic field.

Strong Photoluminescence Enhancement in All‐Dielectric Ge Thin Film Metasurfaces for Integration on the Si Platform

open access: yesAdvanced Optical Materials, EarlyView.
Germanium (Ge) all‐dielectric metasurfaces can be leveraged to strongly enhance the radiative emission from Ge layers grown on silicon‐on‐insulator substrates by industry‐standard processes. At room‐temperature, the narrowband photoluminescence (PL) intensity is enhanced by a factor ∼40× with respect to unstructured films.
