High‐Performance Near‐Infrared Organic Light‐Emitting Diodes Based on Grating‐Structured Hole Transport Layer

Small Structures, Volume 7, Issue 8, August 2026.
High‐performance near‐infrared (NIR) organic light‐emitting diodes (OLEDs) were achieved by incorporating a one‐dimensional Bragg grating into a thermally cross‐linkable hole‐transporting layer via microtransfer molding. The optimized devices exhibit an emission peak at 880 nm, a maximum external quantum efficiency of 1.55%, and a peak radiant exitance

Color‐Pure Organic Luminophores: Characteristics, Definitions, Physical Basis and Fundamental Design Principles

Angewandte Chemie, Volume 138, Issue 30, 20 July 2026.
Color‐pure all‐organic emitters, i.e., with narrow spectral characteristics, are intensively studied for high‐definition organic LEDs and multi‐color bioimaging. In order to guide targeted materials design, this educative review discusses spectral characteristics, proper definitions and units, and the physical basis of spectral broadening, to distill ...

Synthesis and Characterization of a Compositionally Complex Aluminum Garnet Ceramic Scintillator: (Gd,Y,Tb,Lu)3Al5O12:Ce

Journal of the American Ceramic Society, Volume 109, Issue 8, August 2026.
ABSTRACT High‐energy X‐ray radiography plays a critical role in national security as it is used to scan cargo for illicit materials, including special nuclear materials. However, currently used scintillators face cost or performance drawbacks, driving the search for superior alternatives.

How Structural Subtleties Modulate Excited‐State Lifetimes in Cyclometalated Cobalt(III) Complexes: Nonadiabatic Molecular Dynamics Study

Journal of Computational Chemistry, Volume 47, Issue 20, July 30, 2026.
Nonadiabatic trajectory simulations unravel the origin of different relaxation times scales observed for two Co(III) complexes, bearing different alkyl groups at their ligands. ABSTRACT Ultrafast excited‐state dynamics of two Co(III) complexes, bearing different alkyl groups (Co1: Methyl, Co2: Ethyl) at the nitrogen of the imidazole ligand, are ...

Phosphorescence of Heavy, T‐Shaped Pnictogen Trisamides in Solution at Room Temperature in the Near‐Infrared II Region

Chemistry – A European Journal, Volume 32, Issue 27, 17 July 2026.
The unique photophysical properties of heavy T‐shaped Sb and Bi trisamides are reported. A ligand‐to‐pnictogen charge‐transfer excitation from a redox‐active NNN pincer to a vacant pnictogen p‐orbital populates a triplet state that emits in the highly desirable NIR‐II region, with lifetimes up to the µs range.
