采用时间分辨率约为120fs的泵浦探针时间分辨反射光谱，研究了（C2H5）2(CH3)2Sb[Pd(dmit)2]2 （Et2Me2Sb[Pd(dmit)2]2）盐在低温相的光致效应动力学。所观察到的光诱导反射率变化是高效的，光诱导态的光谱形状与二聚体莫特绝缘体的光谱形状相似。此外，光诱导信号中由于相干声子引起的振荡结构反映了结构调制耦合与二聚体态的价态变化（[Pd(dmit)2]2）。我们讨论了这种盐在低温阶段的光致现象的基本动力学。
The dynamics of the photoinduced effect in the low temperature phase of (C2H5)2(CH3)2Sb[Pd(dmit)2]2 (Et2Me2Sb[Pd(dmit)2]2) salt was studied by using pump-probe time resolved reflection spectroscopy with the time resolution of about 120 fs. The observed photoinduced reflectivity change was highly efficient and spectral shape of the photoinduced state was similar to that of dimer Mott insulator. In addition, oscillatory structure in photoinduced signal due to coherent phonon was observed reflecting the structural modulation coupling with valence change of the dimer state ([Pd(dmit)2]2). We discuss the primary dynamics of the photoinduced phenomena in this salt at low temperature phase.
