How to restrain electroplex emission and enhance red emission intensity of Eu3+ complex?
چکیده انگلیسی
The electroluminescence (EL) of lanthanide complex profits from the intramolecular energy transfer from the triplet state of ligand to Ln (III) ions, but electroplex emission between ligand and host material may occur when the energy transfer is inefficient. The electroplex emission is completely restrained when 4-(dicyanomethylene)-2-t-butyl-6-(1,1,7,7,-tetramethyljulolidy-9-enyl)-4Hpyran (DCJTB) and Eu(o-BBA)3(phen) are co-doped in poly (N-vinycarbzaole) (PVK). There are great spectra overlapping between electroplex emission and the excitation of DCJTB. The chromaticity coordinates of EL of co-doped device is kept constant (x = 0.55, y = 0.37) under different driving voltage.
