Temperature‐Dependent Optical Properties of CsCu2I3 Perovskites

Advanced Materials Interfaces, EarlyView.
This work explores the temperature‐dependent optical properties of CsCu₂I₃ nanocrystals using transmittance and photoluminescence techniques. Resonant excitation conditions and energy level modeling reveal critical insights into the self‐trapped exciton emission mechanism.

Electrochemical Modulation of Hole Extraction in NiO/Perovskite Bilayers

Advanced Materials Interfaces, EarlyView.
The influence of hole depletion/accumulation on the hole extraction is evaluated in NiO/perovskite bilayers by transient spectroelectrochemical measurements. Metal‐halide perovskite thin films with different valence band positions are prepared, and the influence of band offset on the hole extraction kinetics is studied.

Crystallization Dynamics of Hybrid Perovskite Mediated by a Biopolymer: From Precursor Solution to Thin Film

Advanced Materials Interfaces, EarlyView.
In order to better understand the complex crystallization dynamics of starch‐assisted metal halide perovskites (MHPs), the properties of colloidal precursor suspensions and the thermodynamic evolution of the crystallization reaction are investigated by a comprehensive set of characterization techniques, from solutions to films.

Influence of Outcoupling Layers on Top‐Emitting Perovskite Light‐Emitting Diodes

Advanced Optical Materials, Volume 13, Issue 8, March 13, 2025.
Top‐emitting perovskite LEDs offer benefits over typical bottom‐emitting architectures, toward lasing, improved thermal management, and on‐chip fabrication compatibility. Outcoupling layers offer a strategy uniquely applicable to top‐emitting LEDs to optimize EQE by improving optical outcoupling.
