Abstract As organic light emitting cathode, MgAg nano-alloy has the advantages of low work function and high stability. Increasing the ratio of Ag and reducing the thickness of MgAg nano-alloy can improve the transmittance of MgAg. Embedding Yb nano-metal layer before MgAg nano-alloy can reduce cathode work function, reduce contact barrier and improve device efficiency. ExpEriments show that under Yb 5 Å/MgAg 120 Å, the device efficiency can reach red 41.4 cd/A, green 94.9 cd/A, blue 103.4 cd/A/CIEy, with low power consumption and long life.
