| 内容記述 | The photoluminescence (PL) lifetime of fac tris(2-phenylpyridine) iridium (Ir(ppy)_3) in tetrahydrofuran has been observed to decrease from 145 to 47 µs at 1.5 K with increasing the magnetic field B from 0 to 10 T. A numerical analysis has been done to explain the magnetic field dependence of the PL lifetime. We use a model of three substates 1, 2 and 3 for the emitting 3MLCT triplet states, where non-radiative one-phonon relaxation is undertaken, and assume the magnetic interaction between the low-energy substates 1 and 2 and neglect the interaction with the upper substates 3. Three PL lifetimes are derived. Good agreement is obtained between the observed PL lifetime and the calculated longest PL lifetime, including the deviation from the B^2 dependence observed above about 6 T. The field dependence is also calculated at various temperatures up to 300 K. Unlike the case of 1.5 K, the PL lifetimes change little at high temperatures. | |||||
