Organic Electroluminescent Diodes Having Pure Tb3+ Spectrum
Organic Electroluminescent (OEL) devices using trivalent terbium (Tb)complex as emitter were fabricated. The cell structure was glass substrate/In SnO(ITO).poly(N vinylcarbazole)(PVK)/Tb complex/Al, the hole transport layer and the emitter were fabricated by spin coating on ITO and vacuum deposition, respectively. The EL spectrum consists of sharp emission lines from Tb 3+ ions. Luminance of 210 cd/m 2 was achieved at drive voltage of 15.4 V. This is the highest luminance so far we know, obtained from the OEL cells with Tb complex as emitter. The theory of rare earth's luminance is discussed through measuring and comparing the cell's spectra and electric property.
