3-4 White light emitting organic device with guest-host type fluorescent emitting materials

Abstract

Guest-host type white light emitting organic devices have been successfully fabricated for the purpose of high efficiency with good chromaticity. In results, the device showed 3.83 V in threshold voltage (@1cd/m^2), 9.33cd/A in current efficiency (@100cd/m^2) and 3.35% in external quantum efficiency with CIE color coordinates of (3.33,0.36).
