In this paper, we first report that an inverted green structure OLED device based on TXO-PhCz, a thermally activated delayed fluorescent material, is implanted with ITO / ZnO as an electron to improve the electron injection into the Alq3 layer. Cs_2CO_3 at 7 nm To further improve the electron injection efficiency.The optimized device with the 25-nm ZnO and 7-nm Cs_2CO_3 layer to achieve the effective injection of electrons, the device showed the best performance, the device current efficiency of 28 ~ (-1) cd A ~ ( -1), the power is 16-1mW -1, and the external quantum efficiency reaches 9.8%. The backward OLEDs based on TADF luminescent materials can be simple due to the excellent stability of their electrode materials and luminescent materials Package, is expected to replace the traditional OLEDs.
