  • Abstract In this study, we investigated optoelectronic properties of white polymer light-emitting diodes. In the first part, we studied the energy transfer mechanism between the host material BP105 and the guest material RP119. By controlling the concentration of the dopant material, with the configuration of ITO/PEDOT:PSS/BP105:RP119/LiF/Al, we achieved the max luminance of 11580 cd/m2,luminance efficiency of 3.07cd/A with the CIE coordinate of (0.34, 0.36).
    In the second part, we added glycerol into HTL(Hole Transporting Layer) in order to enhance the conductivity. The structure of the device is ITO/glycerol:PEDOT:PSS/BP105:RP119(100:2)/LiF/Ca/Al, and the max luminance is 16040cd/m2, the luminance efficiency is 3.46cd/A,CIE coordinate is (0.34, 0.36).
    The luminance of the device with glycerol was 40% increased, the efficiency increased up to 13%. The CIE coordinate keep at (0.34, 0.36) between 9 and 14 voltage.
