摘要：

A Monte-Carlo simulation scheme developed on the basis of the polarization approximation for electron cascade is applied for the investigation of mechanisms of energy conversion in CeF3 starting from VUV photon absorption and lasting untill the thermalization of electronic excitation. The simulation deals not only with electrons in conduction band and holes in valence and core bands but also with excited states of cerium. The profile of the luminescence excitation spectra in the low energy domain strongly depends on the relative position of the 5d, 6s, 4f Ce and 2p F states. (C) 1998 Elsevier Science S.A.
