Abstract

A new rare-earth complex TbY(o-MOBA) 6 (phen) 2 {radical dot}2H 2 O was synthesized, which was used as an emitting material in electroluminescence device. This was doped into poly(N-vinylcarbazole) and two devices were fabricated having structures of (1) Glass/ITO/PVK:RE complex/LiF/Al, and (2) Glass/ITO/PVK:RE complex/BCP/AlQ/LiF/Al. As compared with a different Terbium complex Tb(o-MOBA) 3 phen{radical dot}H 2 O, the photoluminescence and electroluminescence mechanisms were discussed. Bright green emission was obtained from the optimized multi-layer device and the highest brightness reached 124.5 cd/m 2 at the voltage of 23 V.
