Electroluminescent properties of polyurethane derivative with stilbene on the side chain
Four kinds of organic electroluminescent devices (OELDs) were prepared. Two single-layer OELDs: using polyurethane (PU) film (130nm) or PU:TPD (80:20 wt %. 130nm) were spin-coated on ITO substrate. Two double-layer OELDs were also prepared, using two single-layer then vacuum-sublimed Alq3 film (20nm) and Mg:Ag alloy layer as a cathode. Luminance-current density relationships in the single-layer and double-layer devices were discussed. Four kinds of OELDs exhibit strong electroluminescence (EL) in the green spectral region.
