摘要：
A series of white polymer light-emitting devices has been fabricated by using a spiropolyfluorene (SF) blue polymer with an orange Ir complex as a blend system. A SF single polymer host and mixed co-host with CBP (4,4-N,N-dicarbazolebiphenyl) or PBD (2-(4-biphenylyl)-5-(4-tert-butylphenyl)-1,3,4-oxadiazole) are investigated to get high efficiency white OLEDs. A good color coordination of (0.34, 0.36) with a good current efficiency of 1.52 cd/A at 2% doped condition in a CBP mixed co-host system is reported.
