A novel rare earth complex Eu (TTA) 2 (N-HPA) Phen (TTA = thenoyltrifluoroacetone, N-HPA = N-pheny-lanthranilic acid, and phen = 1, 10-phenathroline), which contains three different ligands, was synthesized. The Eu complex was blended with poly N-vinylcarbazole (PVK) in different weight ratios and spin coated into films. The luminescence properties of films were investigated and energy transfer...
A novel organic electroluminescent device was made with the structure of ITO/PVK: Tb 0.5 Eu 0.5 (TTA) 3 Dipy/BCP/Alq 3 /Al(a) which utilized the rare earth complex Tb 0.5 Eu 0.5 (TTA) 3 Dipy as the emitting layer. When it was driven under a direct electric field, 612 nm emission from Eu 3+ and 410 nm emission from PVK were observed. In...
