We synthesized new blue emitting materials as host and dopant for blue phosphorescence device. The synthesized host and dopant was used and doping device was fabricated with following structure : ITO / HTL (x nm) / w-Host: 10wt% w-Dopant (40 nm) / ETL (y nm) / LiF (1 nm)/ Al (100 nm). Here, the thickness of each HTL and ETL was altered for optimization. Among the five fabricated devices, D3 (x=60nm, y=20nm) showed the hightest efficiencies with current efficiency of 12.6 cd/A, power efficiency of 8.27 lm/W and C.I.E of (0.17, 0.29) at 10 mA/cm2.
