Absolute quantum yield (Φ) is one of the most important parameters to evaluate the potential of novel materials. Lanthanide complexes Eu_xGd_1-x(TTA)₃phens are synthesized with the ratio of Gd³⁺ dopant concentration ranging from 10% to 90% to improve the absolute quantum yield. Eu_xGd_1-x(TTA)₃phens possess similar infrared and ultraviolet spectra, showing that they have similar molecular structures. The absolute emission quantum yields of Eu_xGd_1-x(TTA)₃phens are determined using a fluoromax-4 spectrofluorometer equipped with an integrating sphere. The fluorescence lifetimes of the Eu_xGd_1-x(TTA)₃phens are measured in the same experiment. It was found that both absolute quantum yields and fluorescence lifetimes of Eu_xGd_1-x(TTA)₃phens are of quasi-periodic variation with the change of the Gd³⁺ dopant concentrations. The absolute quantum efficiency and fluorescence lifetime vary with respect to the Gd content in an opposite fashion, indicating that the rate of energy absorption by the Eu_xGd_1-x(TTA)₃phens and the conversion to light energy is critical for the absolute quantum efficiency. The radiative rate constant K_r and non-radiative rate constant K_nr are calculated. The dependence of K_r and K_nr on the Gd³⁺ dopant concentrations is very similar to that of absolute quantum efficiency. The radiation rate constant K_r and absolute quantum efficiency have a linear relationship.
