제목 | Electroluminescence Properties of Anthracene Derivatives Utilizing Energy Transfer for OLED |
초록 | Organic electroluminescence devices were made from 1,4-bis-(9-anthrylvinyl)benzene (AVB) and 1,4-bis-(9-aminoanthryl)benzene (AAB) anthracene derivatives. Device structure was ITO/AVB/PANI(EB)/Al and ITO/AAB:DCM/Al. In these devices, AVB, polyaniline(emeraldine base) (PANI(EB)) and AAB was used as the emitting material. 4-(dicyanomethylene)-2-methyl-6-p-(dimethylamino)styryl-4H-pyran (DCM) as red fluorescent dopant and Al as cathode. We studied change of wavelength with concentration of DCM doped in AAB. In doping system, we need to understand forming exciton and energy transfer process to study the change of wavelength. To understand how the energy transfer occurs from host to DCJTB, we measureed the ionization potential (IP) and optical band gap (Eg) by cyclic voltammetry and UV-visible spectrum. We compared difference of luminous efficiency with photoluminescence and electroluminescence spectrum. |
