Putting the “P” Back in Delayed Fluorescence – Silylethynyl Substitution Generates Efficient Pyrene Annihilators for Red‐to‐Blue Photon Upconversion

Advanced Optical Materials, EarlyView.
P‐ or pyrene‐type delayed fluorescence is the original name of triplet‐triplet annihilation. However, pyrene is a poor annihilator. Silylethynyl substitution improves the energetics of pyrene and prevents excimer formation, enabling red‐to‐blue photon upconversion with 29% efficiency. We find tuning substituent steric bulk is key to achieving this high

Enhanced Performance of Inkjet Printed Red Quantum Dot Light‐Emitting Diodes Influenced by ETL Uniformity with Solvent Systems

Advanced Optical Materials, EarlyView.
This study investigates the impact of solvent systems on the uniformity of the ZnO electron transport layer (ETL) in inkjet‐printed electroluminescent quantum dot (EL‐QD) devices. The mixed‐solvent approach effectively suppresses the coffee‐ring effect, enhances charge injection, and improves luminance, ultimately contributing to the optimization of EL‐

Long‐Term Study of Optical Nanoparticles Doped With Yb3+/Er3+ and Transition Metal Ions and their Real Application for Imaging and Temperature Sensing on Triticum Aestivum L.

Advanced Optical Materials, EarlyView.
This work shows a study on SrF2:Yb3+, Er3+ water colloid, additionally doped with transition metals (Sc3+ or Zn2+) to enhance observed emission, tested during 22 weeks of storage in ambient conditions. Due to high stability, excellent optical properties achieved under 975 nm excitation, and negligible phytotoxicity, the nanoparticles are applied for ...

Angle‐ and Polarization‐Tolerant Metasurface Designs Based on the Aperiodic Tiling

Advanced Optical Materials, EarlyView.
A novel aperiodic metasurface design is introduced to mitigate the inherent angle and polarization sensitivity of conventional metasurfaces. By employing a recently discovered aperiodic tiling approach, identical elliptical scatterers are arranged with systematic variations in their spacing and orientation, effectively minimizing spectral reflectance ...
