Selective Directional Enhancement in Gold/Perovskite Quantum Dot Metasurfaces

open access: yesAdvanced Optical Materials, EarlyView.
A thin gold layer can selectively enhance the directional radiation of a perovskite quantum dot (QD)1D metasurface by incorporating hybrid plasmonic excitation and redistributing diffraction orders from substrate to cover. The use of template‐assisted self‐assembly techniques enables breakthrough tunability in radiative properties over large areas ...

Slow Hot Carrier Cooling and Quasi‐Fermi Shift Dynamics in Few‐Layer α‐In2Se3 via Transient Absorption Spectroscopy

open access: yesAdvanced Optical Materials, EarlyView.
Ultrafast transient absorption spectroscopy reveals that α‐In2Se3, a non‐toxic and air‐stable 2D material, demonstrates slow hot carrier (HC) cooling (≈35 ps), comparable to perovskites. This prolonged cooling can enable efficient energy extraction. Comprehensive analysis captures key HC dynamics, such as quasi‐Fermi shifts, many‐body interactions, and

From Photo‐Damage to Self‐Healing in Thin Film Pb‐Iodide Perovskites: Action at a Distance

open access: yesAdvanced Optical Materials, EarlyView.
Fluorescence imaging uncovers pronounced spatial and temporal changes in photoluminescence of halide perovskite films following laser‐induced damage. Modifications spatially extend well beyond the illuminated region and evolve over distinct time scales ranging from seconds to many hours, revealing material‐specific self‐healing pathways. These findings

Supramolecular Design of Polymeric Random Lasers

open access: yesAdvanced Optical Materials, EarlyView.
This research investigates the application of PolyHIPE scaffolds as scattering media inRLs. By modifying the scaffold's morphology, pore size, and surface chemistry, the dye distribution within the material is precisely controlled, achieving a tunable laser threshold.
