英文摘要：

A new phosphorescent material based on the platinum complex has been synthesized. The phosphorescent devices have been fabricated by adopting the ultrathin film technology. The device structure is ITO/NPB（50 nm）/CBP（15 nm）/（ppy）Pt（bcam）（0. 3-2.0 nm）/CBP（15 nm）/BCP（10 nm）/ Alq（20 nm）/Mg：Ag（200 nm）. The relative characteristics of the devices are studied. The peak at 625 nm is the emission spectrum of （ppy）pt（bcam）, and the emission spectrum of （ppy）pt（bcam） almost has no change at different driving voltage,it is obviously that the electrophosphorescent characteristics of （ppy）pt（bcam） are very stable. The highest brightness of phosphorescent device,whose phosphor layer thickness is 0.5 nm,is 8 755 cd/m2 under the driving voltage of 24.25 V, the highest current efficiency is 3.33 cd/A at the current density of 499 a/m2.
