| Abstract(in English) | Phosphorescent organic devices use light emitted from the relaxation of triplet excitons, and high luminous efficiencies have been obtained in green and red devices. Achieving high luminous efficiency in the short wavelength region, which has not yet been attained, is critical to organic EL-used displays and lighting. We have examined the possibility of improving the luminous efficiency through the surface plasmon. We measured the photoluminescence and electroluminescence spectra for two kinds of phosphorescent organic devices. One of the devices used CBP: Ir(ppy)_3 and the other used CBP: Ir(ppy)_3/CBP as the emission layer. Light emission of around 430 nm, which was considered to originate from the surface plasmon, was observed only in the CBP: Ir(ppy)_3/CBP devices. It didn't, however, appear in the CBP: Ir(ppy)_3 devices. It was found that the wavelength of 430 nm was situated at a wavelength longer than the plasma wavelength. |
