Locking in Color: Stable RGB Perovskite Nanocrystal Films via UV Cross‐Linking

Advanced Optical Materials, EarlyView.
Combining block copolymer stabilized lead halide nanocrystals with a UV light‐based cross‐linking procedure yields ultra‐stable nanocrystal thin films, which are resistant to dissolution by organic solvents and impervious to interlayer ion exchange. This allows for the fabrication of stacked layer RGB all‐perovskite white light‐emitting phosphors with ...

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

Advanced 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

Optical Properties of Thin Films of Tin Iodide Perovskite Nanostructures

Advanced Optical Materials, EarlyView.
A comprehensive spectroscopic study of thin films of 3D CsSnI3 nanocrystals (NCs) that coexist with residual 2D Ruddlesden‐Popper nanosheets (NSs) has been performed. Polymer encapsulation enables solid‐state stabilization of the tin iodide perovskite nanostructures, while insight into the energetics and dynamics of the NC and NS excitons is provided ...

Halogen Bonding‐Enabled Stabilization of Copper(I) Cluster Scintillators in Aqueous Environments

Advanced Optical Materials, EarlyView.
A new class of halogen bonding‐strengthened copper(I) cluster‐based X‐ray scintillators is developed, with higher lattice symmetry, reduced trap density, and enhanced stability in polar chemical environments surpassing the performance of halogen‐free counterparts and other conventional scintillators. Abstract Scintillators are essential in applications,

Improving Light Outcoupling and Addressing Measurement Specifics in Perovskite Light‐Emitting Diodes with Light Management Foils

Advanced Photonics Research, EarlyView.
The necessity and feasibility of enhancing light outcoupling in perovskite light‐emitting diodes (PeLEDs) is highlighted. On near‐IR PeLEDs, low‐cost, micro‐textured light management (LM) foils demonstrate boost in light extraction. Optimizing perovskite thickness and the optical cavity in synergy with LM foils is crucial for maximizing performance ...
