Description
Annika Morgenstern and seven co-authors used magnetic field effects to probe hidden loss paths in a third-generation light-emitting device, in a 2024 paper. The device pairs two organic compounds that form a shared excited state and glow blue. Magnetic fields nudge the steps that turn charge pairs into light, so field responses can reveal where energy leaks away.
The team built a new fitting model that joins two curve shapes to cover low and high field effects at once. It beat older fitting formulas in cross-checked tests. Lab measures of light output and current, plus computer chemistry, confirmed that the paired compounds form the intended delayed-glow system. The team also sealed the device in a semi-permeable polymer coat. They point to uses in sensors that read magnetic fields on curved surfaces.
