Effects of Host and Electron Transport Materials on Blue Organic Light-emitting Diodes
The effects of the host materials and electron transport materials on the blue organic light-emitting diodes was studied by researching the effects of energy level and triplet exciton on the performance of devices based on the structure of ITO/MoO

X/Y
/LiF/Al. The high quality double emission layers device with the peak efficiency of 23.78 cd/A was obtained when
X
and
Y
are TmPyPb and TPBI. The results showed that the distribution of exciton and energy transfer can be adjusted and influenced by host materials and electron transport materials.
