| 英文摘要 | Ultrathin Copper (Cu) films are of great research interest to the transparent conducive anodes thanks to their properties of low-cost, low electrical resistivity, high transparency in the visible spectral range, and high work function. In this paper, ultrathin Cu films were thermally deposited on glass substrates as the anodes, which show low sheet resistance of and high transmittance peaking at red spectral range. Red organic light-emitting diodes (OLEDs) with 4-(dicyanomethylene)-2-tert-butyl-6(1,1,7,7- tetrame thyljulolidyl-9-enyl)-4H-pyran (DCJTB) as dopant were fabricated based on the Cu anodes. With the modification of MoO 3 and light enhancement of microcavity effect, the red OLED on Cu anode achieves a maximum current efficiency of 8.85 cd/A and a maximum power efficiency of 8.63 lm/W, which is superior to that on ITO glass. Moreover, oxygen-plasma treatment on the Cu anodes has been found to be able to further increase the transmittance to 75% at 624 nm, leading to high efficiency red OLEDs without MoO 3 modification. The results may pave the way towards a low-cost and tailored transparent anode for red OLEDs in practical applications such as signal lighting and therapy applications. |
