In order to achieve the enhanced hyperfluorescence device performance, we proposed the introduction of ‘suppressing DET layer (SDL)’ to reduce non-radiative process of the Dexter energy transfer process. With insertion of SDL, HF device exhibited the 1.04 times improved efficiency and 2.03 times longer device lifetime than conventional HF device.
