Synthesis of Tris(Dimethylamino)Phosphine‐Based InP Quantum Dots and Their Application in Light‐Emitting Diodes: Progress and Perspectives

open access: yesExploration, EarlyView.
A lot of subtle but key tricks in the synthesis of (DMA)3P‐based InP QDs and device mechanisms were not explicitly explained in the published works. This review firstly provides a comprehensive analysis of the molecular structures and distinct reaction mechanisms of (TMS)3P and (DMA)3P during InP core nucleation.

Spirobifluorene fusion in multiple resonance frameworks enables efficient pure‐red OLEDs with narrowband emission and suppressed efficiency roll‐off

open access: yesFlexMat, EarlyView.
An orthogonal spirobifluorene‐fusion strategy is introduced for B/N/O‐alternated MR frameworks, enabling improved kRISC (5.46 × 103 s−1), high ΦPL (97%), and narrow‐band pure‐red emission. Vacuum‐evaporated OLEDs incorporating this emitter achieve an EQEmax >40% (FWHM = 36 nm) and exhibit exceptionally low efficiency roll‐off at high luminance ...

Flexible plasma‐sintered transparent conducting electrodes fabricated from particle free gold inks

open access: yesFlexMat, EarlyView.
Thin gold electrodes fabricated via particle free metal organic decomposition inks provide a promising alternative to indium tin oxide for flexible devices. Low temperature plasma sintering enables compatibility with polymer substrates while maintaining transparency and sufficient electrical conductivity for optoelectronic applications.

A Prediction Model for One‐Year Disability Risk Among Community‐Dwelling Older Adults in China: Integrating Physical, Metabolic, and Psychosocial Factors

open access: yesHealth Care Science, EarlyView.
Based on a prospective cohort of 1003 older adults, we developed and validated a practical disability prediction model integrating physical, metabolic, and psychosocial factors (AUC = 0.716), presented via a user‐friendly nomogram for community use. ABSTRACT Background Disability in older adults, characterized by progressive limitations in performing ...
