摘要：
The temperature dependence of the lifetime of the singlet excited state in thin films of tris(8-hydroxyquinoline) aluminum (Alq(3)) is investigated. An increase in the excited state lifetime and fluorescence quantum yield with : decreasing temperature from 300K to 77K is observed. A diffusion based single exciton trapping model is used to explain these results.
