Sublimed Eu(dbm)3(Phen), >99.0% purity

Red-orange phosphorescence emitter

Eu(dbm)3(Phen) - tris(dibenzoylmethane)phenanthroline europium(III) - is a typical tenary Eu3+complex with a ligand 1,3- diphenylpropane-1,3-dione and a secondary phenanthroline ligand coordinating to the europium core. Eu(dbm)3(Phen) displays red-orange phosphorescence emission at 615 nm with a narrow bandwidth (color purity) FWHM smaller than 100 cm-1 in OLEDs. Eu(dbm)3(Phen) is preferably co-deposited with a charge transport material to reduce the chance of self-quenching (concentration quenching) and to improve charge carrier mobilities.

Eu(dbm)3(Phen) is also frequently embedded in polyvinylcarbazole (PVK) or mesoporous silica nanoparticles for electroluminescence studies to improve its efficiency and photo stability.
