Phosphorescent OLED device energy levels

Device structure and energy level diagram of green phosphorescent OLED with mixed EML and TBADN Bphen ETL. HOMO energies were obtained as IPs by UPS spectroscopy or as electrochemical oxidation potentials by cyclic voltammetry. LUMO values were estimated from solution-determined redox data. Unless otherwise noted, redox processes were reversible. No reduction was observed for TCTA within solvent window, LUMO of TCTA is significantly higher than the shown value. Irreversible reduction was observed for Bphen LUMO may be up to 0.3 eV higher. ... [Pg.487]
