High CRI and stable spectra white organic light-emitting diodes with double doped blue emission layers and multiple ultrathin phosphorescent emission layers by adjusting the thickness of spacer layer
Autor: Feiyu Yang, Wang Baiqian, Yu Tang, Yuan Qingsong, Fu Xiang'en, Zhiqi Kou
Publikováno v: Organic Electronics. 70:149-154
The color rendering index (CRI) and Commission Internationale de L'Eclairage coordinate (CIEx,y) are significant parameters for the white organic light-emitting diodes (WOLEDs). We fabricate a series of the phosphorescent WOLED devices, in which ther

A study on the concentration and distribution of the mixed host material in the blue phosphorescent OLED with the dual emitting layers
Autor: Zhiqi Kou, Xiaoping Wang, Liping Yang
Publikováno v: Optik. 155:50-55
We have investigated a relationship between the device performance and the mixed host material in the blue phosphorescent organic light-emitting diodes (PHOLEDs) with the dual emitting layers (EMLs). Firstly, a series of devices with EML1 (host mater

Improved efficiency in blue phosphorescent organic light-emitting diodes by the stepwise doping structure
Autor: Changyan Ji, Xiaoping Wang, Liping Yang, Zhiqi Kou
Publikováno v: Optical Materials. 66:399-403
The electro-optical properties of the blue phosphorescent organic light-emitting diodes (PHOLEDs) can be affected by the stepwise doping structure in the emitting layer (EML). A series of multi-EML devices with different doping concentration of blue

Realizing high-performance color-tunable WOLED by adjusting the recombination zone and energy distribution in the emitting layer
Autor: Zhiqi Kou, Baiqian Wang, Lijun Wang, Xu Sun, Juan Zhou, Xiang Chen, Zixuan Zheng
Publikováno v: Journal of Physics D: Applied Physics. 54:265107
Color-tunable white organic light-emitting diodes (CT-WOLEDs) having daylight chromaticity and a wide correlated color temperature (CCT) span can mimic our circadian cycle and realize application for lighting or decoration. The effects of the recombi
