Abstract

The electrical and optical properties of blue organic light-emitting diodes fabricated by utilizing nickel-oxide nano buffer layers between the anodes and hole transport layers were investigated. NiO nanolayer on ITO was prepared by the electrochemical methods. The effects of NiO nanolayer on the device performances were studied. The experimental results show that NiO buffer layer can effectively enhance the probability of hole-electron recombination due to an efficient holes injection into and charge balance in an emitting layer. The sample with Ni deposition time of 30 s has the highest luminance of 42 460 cd/m

maximum current efficiency of 24 cd/A
