英文摘要	low color-temperature (ct) light sources are preferred for physiologically-friendly illumination at night due to their low suppression of melatonin secretion. we fabricated low-ct hybrid organic light-emitting diodes (oleds) by constructing a double emissive-layer (eml) structure, with a blue-red fluorescent-phosphorescent hybrid eml and a green phosphorescent eml, separated by a bipolar inter-layer. by doping a red phosphor in a blue fluorescent mixed-host with a decent concentration, blue and red emissions from the host and dopant, respectively, were obtained. the ct of the optimized device was tuned to less than 2500 k, with the brightness ranging from 100 to 10,000 cd m(-2). in addition, the low-ct oled exhibited much higher efficacy than other low-ct light sources, such as incandescent bulbs and candles. the maximum power efficiency and external quantum efficiency of the hybrid oled reached 54.6 lm w-1 and 24.3%, respectively, which only rolled off to 44.2 lm w-1 and 23.6% at 1000 cd m(-2), with a ct of 1910 k. low-ct oleds with high efficacy provide a promising alternative for night lighting that will safeguard human health.
