摘要：
Rare earth complex with a structure of [Tb（m-MBA）3phen]2·2H2O was synthesized,which was used as light-emitting material in electroluminescence. The terbium complex was dispersed in poly （N-vinylcarbazole） （PVK） as an emitting layer which is made by spin coating. Two kinds of devices were fabricated with structures: as following device Ⅰ: glass/ITO/PVK: terbium complex/PBD/LiF/Al, and device Ⅱ: glass/ITO/PVK: terbium complex/AlQ/LiF/Al. The photoluminescent （PL） and electroluminescent （EL） behaviors of the devices were investigated. Bright green emission can be obtained from optimized device Ⅱ,and the highest EL brightness of it reaches 140 cd·m （-2） at the voltage of 20 V.
