A top-emitting organic light-emitting device (OLED) and a method for preparing the same are provided. The top-emitting organic light-emitting device comprises, stacked in sequence, a substrate (101), an anode layer (102), a self-assembled modification monolayer (103), a hole-transport layer (104), a light-emitting layer (105), an electron-transport layer (106), an electron-injection layer (107) and a cathode layer (108). The self-assembled modification monolayer (103) is formed of alkanethiol having a general formula CH3(CH2)n—SH. Utilizing the self-assembled modification monolayer (103), the work-function of the anode layer (102) is increased, the hole-injection barrier between the anode layer (102) and the hole-transport layer (104) is reduced, the start-voltage of the OLED is decreased, and the luminous efficiency of the OLED is improved. |
