The effect of fourth color component on enhancement of color gamut

open access: yes2017 IEEE Photonics Conference (IPC), 2017
In this work, we simulate and analyse the peak emission wavelength and full-width-at-half-maximum (FWHM) parameters of nano emitters using four-color mixing approach to provide a tetragonal area as large as possible in CIE-1931, reaching over 160% NTSC area using emitters having 30nm FWHM.

Dual‐Mode Electrophoretic Displays Enabled by Quantum Dot‐Decorated PR48:2 Pigment Particles and TiO2 for All‐Weather Visibility, Excellent Bistability, and Enhanced Readability

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study presents a novel quantum dot electrophoretic display (QDEPD), which combines electro‐controlled reflection and optically‐triggered emission to achieve efficient multi‐modal switching within a single pixel. By incorporating multi‐component nanostructures, the system enhances functional integration and multi‐modal response capabilities.

CD8+ T‐cells, CD86+ macrophages and TNF‐α signalling pathways are correlated with fetlock osteoarthritis in racehorses

open access: yesEquine Veterinary Journal, EarlyView.
Abstract Background There is emerging evidence for the role of the immune system in osteoarthritis (OA) pathophysiology; however, little is known about how immune cells and the synovial transcriptome are altered in naturally occurring equine OA. Objectives To evaluate synovial fluid (SF) and synovial membrane (SM) immune cell populations and the SM ...

Programmable luminescent platform based on carbon quantum dots enables wavelength‐multiplexed optical data storage and encryption

open access: yesFlexMat, EarlyView.
A carbon‐quantum‐dots (CQDs)‐based programmable luminescent platform is proposed for multidimensional optical information encryption and high‐capacity data storage by leveraging wavelength‐division multiplexing. Furthermore, a prototype tri‐layer optical disk is demonstrated, where data written via laser ablation on different CQD layers are retrieved ...

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 ...
