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

open access: yesAdvanced 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.

open access: yesAdvanced 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 ...

Nd(III)‐Based Temperature‐Independent Manometer and Pressure‐Independent Thermometer with Slow Relaxation of Magnetization

open access: yesAdvanced Optical Materials, EarlyView.
The Neodymium(III) macrocyclic complex [NdL(CF3SO3)3] serves as a non‐contact, bifunctional sensor for temperature and pressure, displaying field‐induced Single Molecule Magnet (SMM) behavior. At 3 GPa, triflate rotations halt, triggering a disorder‐order phase transition from centrosymmetric phase α to noncentrosymmetric high‐pressure phase β.
