Organic molecule thienyl diketone: greater than 10X faster phosphorescence efficiency, paves way for rare metal-free applications

https://phys.org/news/2024-07-molecule-shatters-phosphorescence-efficiency-paves.html

"high-efficiency phosphorescence without using rare metals (iridium, platinum)... occurs when molecule transitions from high- to low-energy state... often competes with non-radiative processes where molecule loses energy as heat, slowing phosphorescence, efficiency... solves this issue, while rivaling the speed and efficiency of rare metal-based materials...
