Molten Zinc Coordination Polymer Glass as a Host for Stable and Processable Optical Dye Composites

open access: yesEcoEnergy, EarlyView.
Zinc‐based coordination polymer glass is employed to suppress aggregation‐caused quenching (ACQ) and enhance molecular stability, enabling improved luminescence performance in the solid state. The emission color of the hybrid composites can be tuned by varying the incorporated guest molecules, while the glass matrix effectively prevents aggregation and

Liquid‐Phase Synthesis of Halide Solid Electrolytes for All‐Solid‐State Batteries Using Organic Solvents

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study develops a scalable and universal liquid‐phase synthesis method of halide solid electrolytes using nitrogen‐containing solvents. The Li2YCl5−yBry (y = 0, 2, and 5) solid electrolytes synthesized via pyridine solvent exhibit an ionic conductivity over 1 × 10−4 S cm−1 at 25 °C.
