  • Abstract Tandem structure for OLED application with HAT-CN:Alq3 interlayer is studied. It has been found that tandem cell with such interlayer structure has a low turn-on voltage as comparing to other types of interlayer structure. Three research topics are included in this research:
    (1) Study of carrier generation , carrier transport , and other optoelectronic properties for tandem cells with HAT-CN:Alq3 interlayer.
    (2) Study of white OLED device with single emitting layer and HAT-CN:Alq3 interlayer.
    (3) Study of electroluminescence property of top and bottom device of a tandem cell with HAT-CN:Alq3 interlayer.
    Experimental results show that electron transport is slowing down with increasing Alq3 concentration in the HAT-CN:Alq3 interlayer. However concentration of Alq3 in the interlayer does not affect transport property of hole. A white OLED with HAT-CN:Alq3 interlayer can reach 40,500 cd/m2 at 2180 mA/cm2 with a power efficiency of 1.96 lm/W and CIE coordicate of (0.34,0.32).
