TIAN Miao-miao, LIU Xing-yuan. High Efficiency Tandem Organic Light-emitting Diode Based on a New Charge Connecting Layer[J]. 发光学报, 2010,31(5): 651-654DOI:
A tandem organic light-emitting diode (OLED) with a new charge generation layer of m-MTDATA:MoO
3
has been studied. Compare to the OLED with single electroluminescence unit
the tandem OLED shows an enhanced luminance and current efficiency by a factor of nearly 1. The maximum luminance and the maximum efficiency of tandem OLED are 83 210 cd/m
2
and 30.06 cd/A
respectively.
