Popis:	From the basic structure of a red organic light-emitting device (OLED) with peak wavelength of 624 nm, blue emission with peak wavelength of 457 nm could be obtained by simply excluding an emissive layer of the red device. This technology makes it possible to fabricate two color OLEDs of red and blue simultaneously so that the manufacturing cost can be greatly reduced in the application devices due to simple structure and saving of the used materials. The experimental results showed the maximum current efficiencies of 16.7 cd/A and 4.8 cd/A and the luminance of 4600 cd/m2 and 7300 cd/m2 at 8V in the red and blue devices, respectively.
