Recent advances and prospects for high‐efficiency blue hot exciton organic light‐emitting diodes

FlexMat, EarlyView.
Blue organic light‐emitting diodes (OLEDs) face great challenges in achieving the balance between color purity, device efficiency, and stability. Hot exciton materials offer a solution by rapidly converting non‐emissive triplet excitons into singlet ones through a high‐lying reverse intersystem crossing process.

Gradient‐Structured Polymer Fiber Mats for Broadly Tunable Multicolor and White Lasing

Laser &Photonics Reviews, EarlyView.
Hierarchically engineered electrospun fiber mats containing separated red, green, and blue dyes enable highly tunable multicolor and white random lasing. Spatially controlled dye distribution suppresses energy transfer, allowing precise color adjustment across wide color gamuts and accurate reproduction of daylight white standards.

Practical considerations for pathologists when selecting digital pathology systems: an ESDIP guide

The Journal of Pathology, EarlyView.
Abstract The implementation of digital pathology (DP) has been reported across academic, public, and private laboratory settings, providing valuable insights into workflow transformation. However, comparatively little guidance exists on how DP systems should be evaluated prior to acquisition and deployment.

Kinetically Controlled Direct In Situ Photolithography of Perovskite Color‐Conversion Layers

Small, EarlyView.
Kinetically controlled direct in situ photolithography (KC‐ISP) enables high‐resolution patterning of micrometer‐thick perovskite color‐conversion layers. By regulating thiol–ene reaction kinetics and redistributing precursors within the polymer matrix, lateral curing is suppressed and spatially selective crystallization is achieved.

The effect of fourth color component on enhancement of color gamut

2017 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.
