We report a successful fabrication of organic light-emitting diodes (LEDs) with electron injecting electrodes prepared by the radio frequency (rf) magnetron sputtering technique. These LEDs consist of a poly(methylphenylsilane) and a tris-(8-hydroxyquinoline) aluminum (Alq3) layer successively formed on an indium–tin–oxide coated glass, and either an aluminum or magnesium electron injecting electrode. Substantial improvements were observed in such device characteristics as intensity and durability of electroluminescence for LEDs with an rf-sputter-deposited electrode as compared to those with a vacuum-heat-deposited electrode.
