摘要：

Transient optical emission spectra of biphenyl-1,2,4,5-tetracyanobenzene crystal doped with TCNQ have been investigated in the (77÷300) K temperature range. Host prompt fluorescence lifetimes have been measured by cross-correlation phase fluorometry. The decay signal is fitted by a biexponential function whose coefficients are strongly dependent on temperature. A thermal activation energy of 300 cm-1 for the diffusion of singlet exciton has been determined. © 1990 Società Italiana di Fisica.
