Faster organic phosphorescence for better OLED and smartphone diplays without the need for heavy metals

https://news.umich.edu/faster-organic-phosphorescence-for-better-display-tech/

"replaces heavy metal with hybrid layering 2D molybdenum/ sulfur over 2D organic light emitting material achieving stable, fast phosphorescence, lower cost, eco-friendlier... LEDs maintain sharp color/ contrast... phosphorescence 3X more efficient than fluorescence because it harnesses 100% of excited electrons instead of 25%, speeds up light emission 1,000X without having weak metal-organic ligand bonding, extending lifetime... OLEDs, smartphones"
