摘要

Rare-earth ternary complexes Tb_1−xEu_x(m-NBA)₃Phen (X = 1, 0.25, 0.5, 0.75, 1.0) were synthesized and characterized by IR, DTA–TG, UV, fluorescent spectra and elemental analysis. It was found that luminescence of Eu³⁺ complex was enhanced by doped with Tb³⁺. It is proved by TG curve that the complexes are stable, ranging from ambient temperature to 360 °C in air. The organic–inorganic combined structural device was fabricated, and the electroluminescence intensity of the combined structural device was improved compared with the device of the purely organic components.
