Robust, Strongly Luminescent, and Highly Dispersible Hybrid Materials
​ ​ Hybrid structures incorporating ionic and coordinate bonds Invention Summary: Hybrid structures built on cluster based charge-neutral CumIm modules (e.g. Cu4I4 cubane tetramer) typically have higher luminescence efficiency compared to inorganic modules with higher dimensions, such as a 1D chain or 2D layer of (CuI)∞. Structures with...

Novel Rare Earth Element-Free Lighting Phosphors with High Quantum Efficiency and Enhanced Thermal and Photostability
​ ​ Invention Summary: Light-emitting diodes (LEDs), the main branch of solid-state-lighting (SSL) technology, are rapidly replacing conventional lighting sources because they are much more energy-efficient and longer-lasting. However, current LED devices rely heavily on rare-earth elements, which are in severe cost and supply risk in addition...

Stable phosphorescent OLEDs for lighting applications
Novel OLEDs with higher photoluminescence stability Invention Summary: Organic light-emitting diodes (OLEDs) are an emerging display and lighting technology, especially for large area and architectural lighting. Phosphorescent OLEDs are very energy efficient, besides, they don’t suffer from the “green gap” in their emitting spectra...
