| 抄録: | Organic electroluminescent devices with saturated red emission were developed using 6,13-diphenylpentacene (DPP) doped into tris(8-hydroxyquinolinato) aluminum III (Alq_3). DPP exhibits a narrow emission spectrum giving rise to a saturated red peak, centered around 625 nm, with excellent chromaticity coordinates (x = 0.63 and y = 0.34) in accordance with the Commission Internationale de l'Eclairage. An absolute photoluminescence (PL) quantum yield (Φ_PL) of ～30% was measured for a composite film of 0.55 mol % of DPP doped into Alq_3. An electroluminescence (EL) quantum efficiency of 1.3% at 100 A/m^2, close to the estimated theoretical limit (1.5%), was measured for an unoptimized device structure that consists of an active emissive layer sandwiched between hole- and electron-transport layers. In addition, the EL quantum efficiency is constant or stable over a wide range of current densities (1-1000 A/m^2) or luminance values (1-1000 cd/m^2). |
