摘 要: | A new kind of TiO2 self-assembled nanometre material has been fabricated and is used as a hole-injecting buffer layer in organic electroluminescent devices.The luminance and the efficiency of a devicy individually rises from 1500cd/m^2 to 5000cd/m^2 and from 2.0cd/.A to 3.92cd/A at the current density of 100mA/cm^2.The enhancements in brightness and efficiency are attributed to an improved balance of hole and electron injections due to blocking of the injected holes by the buffer layer and a more homogeneous adhesion of the hloe transprting layer to the anode.
