Strategies for Enhancing Efficiency and Operational Stability in Green Phosphorescence-Sensitized Fluorescence (PSF) Organic Light-Emitting Diode (OLED) Technology. [PDF]
Efficiency and stability of PSF OLEDs can be obtained by improving the terminal emitters (TE's) extinction coefficient (ε) and a large spectral overlap (J) with PS emission, combined with a dual‐channel energy transfer process, with a high T1 exciplex host system to suppress the back energy transfer (BET) from PS to the host and a high intrinsic stable
