摘要：
We report on an interpretation of the 4f -* 5d absorption and fluorescence spectra as well as the previously unreported intra-4f transitions between the Stark levels of the 2F5/2 and 2F7/2 multiplets of the single seven-fold coordinated, C1 symmetry site for Ce3+ in Y2SiO5. Further, We also give the corresponding crystal-field parameters determined by fitting to the observed energy level data and the ground state Zeeman g tensor obtained from previously reported electron paramagnetic resonance (EPR) measurements. Finally we present a temperature-dependent analysis of the linewidth and position of the 4f -* 4f absorption lines.
