Abstract
The electroluminescence devices (ITO/NPB/emitting layer/BCP/Mg:Ag) based on 1, 4-bis (4-N, N-methylamino styryl) naphthalene as emitting layer have been designed by the energy band matching principle. Current efficiency, power efficiency, brightness and stability of the devices have been enhanced when the thickness of hole countercheck layer (BCP) is increased to 60 nm in comparison with 30 nm. The three-layer electroluminescence devices exhibit the maximum brightness of 2100 cd/m2 and the largest power efficiency of 0.4lm/W respectively.
