Organic light emitting diodes have been expected to serve as one of the alternatives to fluorescent or incandescent lamp. Upper limit of internal quantum efficiency of a fluorescent OLED is considered to be 25% because 75% of excitons quenched as non-radiative triplet excitons. We aim improvement of the efficiency of fluorescent OLEDs with triplet-singlet conversion process.
