A self-assembled monolayer (SAM), 4-fluorothiophenol (4-FTP), is employed to modify the Ag anode of a top-emitting polymer light-emitting diode (T-PLED) to enhance the hole injection and the performance of a T-PLED device. The results show that the reflectivity of the Ag anode does not decrease due to the formation of a SAM. A brightness of 68 981 cd m2 and a luminous efficiency of 10.3 cdA have been achieved for the 4-FTP-modified device. The improved performance is attributed to the work function increase of the Ag/4-FTP anode due to the presence of fluorine atoms at the outer surface of the modified anode.
