Theoretical calculation is used to investigate characteristics of organic light emitting materials in this thesis. 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.
