Abstract

Abstract Electroluminescent devices were fabricated using poly(methyl methacrylate) (PMMA) molecularly doped with triphenyldiamine derivative and tris(8-quinolinolato)aluminum(III) complex (Alq). A cell structure of glass substrate/indium-tin-oxide/doped PMMA/Mg: Ag was employed. Green emission with luminance of 920 cd/m2 was achieved at a drive voltage of 17 V. The EL color was tuned to blue-green and yellow-orange by further doping the PMMA layer with suitable organic dyes.
