Abstract:

Symmetrically configured a.c. light-emitting SCALE 5-layer devices having the configuration MEBPEBITO, where MAl, Cu or Au, EBpolyaniline emeraldine base, Ppoly2,5-dihexadecanoxy phenylene vinylene pyridyl vinylene or PPV-PPyV, and ITO indium-tin oxide glass, show electroluminescent properties in both forward and reverse bias modes. In the absence of emeraldine base, in the case of aluminum and copper, electroluminescence is observed only in the forward bias mode in the case of gold no electroluminescence is observed in either forward or reverse bias modes. The electrical properties of the 5-layer devices MAl, Cu are most surprising since their total resistance at a given applied voltage is significantly less than that of the corresponding devices in which the two polyaniline insulator layers are not present.
