Abstract: The photoluminescent(PL)and electroluminescent(EL)properties of a series of ligand emitting rare earth complexes(including Y3+,La3+,Gd3+ and Lu3+)were systematically studied.These complexes have the same anionic ligand,1-phenyl-3-methyl-4-isobutyryl-5-pyrazoloneate(PMIP),and three neutral ligands,triphenyl phosphine oxide(TPPO),2,2′-dipyridine(Bipy)and phenanthroline(Phen).Measured with 60 nm thin film of these complexes vaporized in vacuum on quartz substrates,a good regularity in the PL properties was observed.For rational comparison,the same structural EL devices based on these complexes,ITO/PVK(40 nm)/the complex(80 nm)/Mg:Ag(200 nm)/Ag(100 nm),were fabricated.Excluding the exciplex emission happens,the EL luminance usually increases with the increasing of PL efficiency.
