The research shows that the doping of Yb in Liq can effectively improve the photoelectric performance of the device. When the doping ratio of Yb is 1.85%

the device performance is the best. Under the condition of 0.25 mA/cm

the starting voltage is 3.65 V

the maximum brightness is 26 720 cd/m

the maximum current efficiency is 87.07 cd/A

the maximum power efficiency is 74.89 lm/W

and the maximum external quantum efficiency is 24.07%. Compared with the reference device

the maximum brightness increases by 2 181 cd/m

the maximum current efficiency increases by 18.42 cd/A

the maximum power efficiency increases by 10.6 lm/W

and the maximum external quantum efficiency increases by 5.27%.
