摘要: Abstract The fluorene derivative included in polymers has been reported to emit highly efficient blue luminescence electroluminescent devices (ELDs). monomer is advantage of over the term easy processability and long stability. characteristic emission peaks observed at around 500nm from with without 8-Hydroxyquinoline aluminum salt (Alq3) was studied. fluorescence 2-(4-biphenylyl)-5(4-tert-butyl-phenyl)-1,3,4-oxadiazole (PBD) did not extend 500nm. low energy transition ELDs, very similar results obtained device ITO/CuPc/TPD/PBD/Al. can be resulted local electric field generated by space charge under high field. stability improved when PBD layer layered derivative. improvement correlated smooth surface
