Selective Directional Enhancement in Gold/Perovskite Quantum Dot Metasurfaces
Advanced 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 ...

Advanced 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
