dc.description.abstract | Lead-free, non-toxic transition metal-based phosphorescent organic-inorganic hybrid (OIH) compounds are promising for next-generation flat-panel displays and solid-state light-emitting devices. In the present study, we fabricate highly efficient phosphorescent green-light-emitting diodes (PHOLEDs) using the lead-free, non-toxic, zero-dimensional OIH compound [(H2C=CHCH2)(C6H5)(3)P](2)MnBr4 (1), which exhibits an emission peak at 516 nm and a long lifetime of 441 mu s. The long lifetime indicates the phosphorescent emissive nature of 1. Density functional theory calculations confirm that the narrow green emission from 1 is due to the highly localized electronic states of the valence and conduction bands. A flexible green-light-emitting phosphorescent substrate is successfully fabricated from 1 using a nylon membrane, indicating that 1 has a significant potential for use in flexible optoelectronic devices. By engineering the organic hole and electron transport layers, we achieve a highly efficient all-vacuumdeposited PHOLED with a current efficiency of 24.71 cd A(-1), a power efficiency of 20.61 lm W-1, and an external quantum efficiency of 7.12%. Together, our findings will pave the way for the development of high-performance Mn(II)-based LEDs. | - |
