The complexes show phosphorescence emission maxima from 450 nm to 502 nm in CH 2 Cl 2 solution with the quantum efficiencies from 13.2% to 51.1%, respectively. All the complexes exhibit emissions peaked from 482 nm to 503 nm in solid state, respectively. By using these complexes solid powder as emitters, the light emitting diodes with the blue GaN material as substrate were prepared. The CIE color coordinates are in blue-green and yellow-green regions for the LED based on all the complexes. The maximum light emitting efficiency value for (ftfmppy) 2 Ir(TSAP) based LED is 5.6 lmW -1 , and the color of (dfppy) 2 Ir(PSAP) based LED (0.316, 0.431) is almost near-white. 2-(苯磺酰基)苯乙酮 铱配合物 磷光材料 光致发光 2-(phenylsulfonyl) acetophenone iridium complexes phosphorescent materials photoluminescence KANG D M, KANG J W, PARK J W, et al..
