摘要	By changing the coordinating metal in the electron accepting materials, we systematically studied the heavy metal effect on the performance of the exciplex with m-MTDATA as an electron donor. It is found that the environmental heavy metal effect of Lutetium could enhance the photoluminescence and electroluminescence intensity of red exciplex two times by decreasing its decay time and increasing its radiative efficiency. This shortened decay time could enhance the exciplex intensity by preventing it from phonon quenching effect under high temperature (300 K). As a result, high external quantum efficiency of 3% of pure red exciplex based OLED was achieved. While the paramagnetic metal Gadolinium might decrease the radiative quantum yields of both singlet and triplet exciplexes.
