We have investigated the effect of hole transporting materials in phosphorescent white polymer light-emitting diodes. The doping of a hole transporting material TCTA (4,4 0 ,4 00tris(N-carbazolyl)-triphenylamine) resulted in enhanced luminance and efficiency while the doping of other hole transporti
