概要
- 論文の詳細を見る
The transient response of the second order optical process is studied for alocalized electron-phonon system the stationary response of which was discussedin the preceding paper. We make use of the stochastic theory to project thedynamics of the whole lattice system onto the stochastic motion of the appropri-ately chosen relevant mode. The time-resolved emission spectrum is calculatedfor our model of vibrational relaxation which can be handled analytically. Thetime-dependent behaviors of various components of the secondary emissionare clarified. The temporal characteristics of Raman (or Rayleigh) scatteringcomponents are determined by the phase memory time. On the other hand, theluminescence spectrum is composed of the ordinary and hot luminescence com-ponents. The characteristic time constant of the former is given by the radiativedamping rate and that of the latter by the sum of the vibrational relaxation rateand the radiative damping rate.
