چکیده انگلیسی
First, binary and ternary doping system of terbium and/or europium β-diketonate complex doping in poly(N-vinylcarbazole) (PVK) was studied. Energy transfer was analyzed in such complicated doping system. In such a complicated system, inter-molecular energy transfer from PVK to Tb(DBM)3Phen(TbDP) and Eu(DBM)3Phen(EuDP), and from TbDP to EuDP exists. The color changed by adjusting the mixing ratio of dopants concentration and excitation wavelength. Further, in the ternary doping system, it is found that white light could be obtained by optimizing the excitation of different wavelength.
