Analytical Sciences, 1987 The effect of the solid support on thermally activated delayed fluorescece (TADF) was investigated. Comparison of the molecular structures of supports and consideration of the energy levels of the absorption band and the fluorescence, and of lifetimes of emissions allowed the postulation of certain molecular criteria for the supports of TADF.

Thermally Activated Delayed Fluorescence Coinage Metal Cluster Scintillator
ACS Central Science, 2023 X-ray scintillators are widely used in medical imaging, industrial flaw detection, security inspection, and space exploration. However, traditional commercial scintillators are usually associated with a high use cost because of their substantial toxicity and easy deliquescence.

Advanced Functional Materials, EarlyView.This study demonstrates that memristors can replace conventional 2T–1C driving circuits with simplified 1T–1 m architectures by exploiting resistance switching. With ultra‐low switching voltages (< ±0.2 V) and multi‐level resistance states, the memristors precisely control the current injected into organic light‐emitting diodes (OLEDs).

Exciton Binding Energy of Phosphorescent Emitter Molecules in Organic Light‐Emitting Diodes
Advanced Functional Materials, EarlyView.Energy level alignment is key to efficient OLED design, yet determining LUMO energies remains challenging. A methodology based on field‐induced dissociation and kinetic Monte Carlo simulations is presented to extract LUMO energies of iridium‐based phosphorescent emitters from their exciton binding energy.
