内容記述 | We have successfully fabricated polymer light-emitting diodes (PLED), operating in the ultraviolet wavelength region. The active region consists of a single layer host polymer material doped with a guest low-weight molecule material. The host material is Poly[methyl methacrylate-co-(7 -(4-trifluoromethyl)coumarin acrylamide)] (PCA), whose lmax is in the ultra-violet region of 339 nm, while the guest material is a hole-transporting material, N,N'-Bis(3 -methylphenyl)-N,N'-diphenyl benzidine (TPD). In the case of low-TPD-doping-densities, PLEDs consisting of a PCA layer do not emit any electroluminescence (EL) signal. With an increase of TPD-doping-densities, however, EL signals are observed. In particular, we have found the suitable TPD-doping density, at which the peaking wavelength in the EL spectrum becomes shortest and the EL intensity becomes maximum. The observed shortest wavelength is about 400 nm. If the TPD-doping-density is larger than the suitable value, the peaking wavelength becomes longer and the intensity becomes weak. This result clearly indicates that the carrier injection efficiency into the largest radiative site of PCA can be improved by large TPD-doping. | |||||||||||
