| 英文摘要 | Ultra-high color rendering index (>90) is considered to be crucial for lighting in museum, studio, art gallery, medical, and wide-color-gamut display. However, all relevant works reported to exhibit ultra-high color rendering index suffer from a low efficiency and serious efficiency roll-off. In order to achieve ultra-high color rendering index and maintain high device efficiency at the same time, we incorporate four organic dyes in an elaborate device structure. The resulting white organic light-emitting diode exhibits rather high color rendering index up to 94 over a wide brightness range and yields electroluminescence efficiencies up to 14.2%, 26.0 cd/A, and 21.9 lm/W at the brightness of 1000 cd m(-2), which are the highest values reported to date for such ultra-high color rendering index white organic light-emitting diodes. In addition, the current issue on efficiency roll-off is well resolved in the resulting device. The critical current density j(c) is as high as 203 mA cm(-2). (C) 2014 AIP Publishing LLC. |
