Poly(N-vinycarbazole) (PVK)/tris(8-hydroxy)-quinoline-aluminum (Alq^sub 3^) bilayer diodes were deposited by vacuum evaporation onto SnO^sub 2^ coated glass substrates. After deposition of an aluminum upper electrode, the diodes were studied by current-voltage (I-V) and electroluminescence-voltage (...
