Ohmic contact-providing compositions

A conductor comprising:

• a) a substrate and thereover, b) an ohmic contact-providing layer comprising a fluorinated carbon filled fluoropolymer and thereon, c) a charge transport layer.

A conductor comprising a charge transporting layer and thereover, an ohmic contact-providing layer comprising a fluorinated carbon filled fluoropolymer.

A light emitting diode comprising:

• a) a substrate selected from the group consisting of semitransparent aluminum and semitransparent magnesium and thereover, b) an electron transport layer comprising a compound selected from the group consisting of 8-hydroxyquiniline aluminum, 2-biphenyl-5-p-t-butylphenyl oxadiazole, and derivatives thereof, and provided on the electron transport layer, c) an optional emitter layer comprising at least one fluorescent dye material and provided thereon, d) a hole transport layer comprising an alkyl amine/polycarbonate, and thereon, e) an ohmic contact-providing layer comprising a fluorinated carbon filled fluoropolymer, wherein the fluorinated carbon is of the formula CF.sub.x, wherein x represents the number of fluorine atoms and is from about 0.02 to about 1.5.

A process for providing an ohmic contact comprising providing a substrate, and thereover a charge transport layer and a fluorinated carbon filled fluoroelastomer layer.
