摘要：
The excitation energy transfer (EET) from polystyrene (PS) to anthracene in 1,4-dioxane solution was investigated as a function of the concentration of the acceptor. The experimental quantum yield of EET is higher than that obtained from Förster's theory, but is in good agreement with the theory of Bojarski and Domsta, which takes into account the resonant excitation energy migration in the donor. Moreover, the experimental results show that the intermolecular interactions between PS molecules lead to the formation of excimer sites which act as excitation energy quenchers due to their lower quantum yield. © 1990.
