Thin lithium fluoride (LiF) interlayers between the low work function electrode and the
electron transport layer in organic light emitting diodes (OLED) result in improved device
performance. We investigated the electronic structure of LiF coated Al and Pt electrodes by x-
ray photoemission spectroscopy (XPS) and ultraviolet photoemission spectroscopy (UPS).
Thin LiF films were grown in several steps onto Ar+ sputtered Al and Pt foils. After each
growth step the surfaces were characterized in situ by XPS and UPS measurements. After …
