Fluorene‐based blue emitters: On the path to electrically pumped organic lasers

open access: yesFlexMat, EarlyView.
Electrically pumped efficient operation remains unrealized, a major challenge in optoelectronics. Fluorene‐based blue‐emitting semiconductors are promising gain media, thanks to their structural tunability and favorable emission properties. This review summarizes recent advances, highlights their reliability and versatility in lasing, and outlines key ...

Donor‐acceptor fractal synergy: Decoding self‐similarity for stable organic photovoltaics

open access: yesFlexMat, EarlyView.
Morphological congruence between donor and acceptor refines the fractal structure of bulk heterojunction films and enhances their self‐similarity. This optimized multiscale morphology preserves charge‐transport pathways against external disturbances, suppresses structural degradation, and improves the operational stability of organic solar cells while ...

Recent Advances in Photonic Bound States in the Continuum: From Fundamentals to Engineering and Implementation

open access: yesLaser &Photonics Reviews, EarlyView.
This review summarizes recent progress in meta‐photonics with a focus on bound states in the continuum (BICs) as a powerful platform for light confinement and control. It covers fundamental concepts, design strategies across optical regimes, symmetry breaking for practical quasi‐BICs, tunable and AI‐assisted BIC devices, and emerging applications in ...
