Stacked GDI602(691)/GDI602(Rubrene) 형광층을 갖는 2-파장 유기발광소자
Two Wavelength OLED with the Stacked GDI602(691)/GDI602(Rubrene) Fluorescent Layer
E-mail:
A new organic light emitting device(OLED) with two peak wavelength(blue and yellow) emission was fabricated using the selective doping in a single fluorescent host , and its electrical and optical characteristics were investigated. The fabricated device showed the luminance and efficiency of 1600 Cd/m2 and 2.4 lm/W under the applied voltage of 10V, respectively. And its electroluminescent spectra had two peak wavelengths of 470nm and 560nm emitting bluish white light. The OLED with dual wavelength emission in this experiment is likely to be developed as a white OLED with simpler fluorescent system than conventional devices.
