Density of states, difference of Gibb’s free energy, energy levels, electron population and molecular orbital are calculated and compared with experimental results. Four materials: Alq3-Li complex, Alq3-Cs complex, SubPc co-doping with LiF and SubPc doped NPB are discussed. Gap states are observed for these materials. N-type doping effects are found for Alq3-Li complex, Alq3-Cs complex and SubPc co-doping with LiF. They can be used in cathodes to get better electronic properties. SubPc doped NPB is used in anodes.1623548 bytesapplication/pdfen-US8-?基??鋁錯合物氯化硼亞?菁有機發光二極體Alq3 Li Cs SubPC NPB OLED gap state complexthesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/253742/1/ntu-99-R97941020-1.pdf
