用时间相关单光子计数法研究了有机半导体四苯(膜厚160 nm)中激子在15~300K温度范围内的能量弛豫。众所周知，时间常数为∼7 ns的三重态激子的驰豫伴随着一个较快的驰豫过程，时间常数从260ps到1.2 ns，取决于温度和波长。
The energy relaxation of excitons in the organic semiconductor tetracene (film thickness 160 nm) is studied by photoluminescence from 15 to 300 K using time‐correlated single‐photon counting. The well‐known relaxation of triplet excitons with time constant ∼7 ns is accompanied by a faster relaxation process with time constants ranging from 260 ps to 1.2 ns, depending on temperature and wavelength.
