Novel techniques for characterization of degradation in polymeric light emitting devices
Durability of the polymer light emitting device is a key for the industrial application. The durability depends on the degradation procedure of the device. The degradation of the device initiates with the dark spot that is the non-emissive portion of the polymer layer. Formation process of dark spots during the device operation in polymeric light-emitting diodes (PLEDs) has clarified by in-situ measurement with the interferometer, time-resolved confocal laser scanning microscope, and other various analytical instruments.
