Intra- and inter-configurational electronic transitions of Ce3+-doped Y2SiO5 : Spectroscopy and crystal field analysis

Abstract

We report on an interpretation of the 4 f → 5 d absorption and fluorescence spectra as well as the previously un-reported intra-4 f transitions between the Stark levels of the 2 F 5/2 and 2 F 7/2 multiplets of the single seven-fold coordinated, C 1 symmetry site for Ce 3+ in Y 2 SiO 5 . 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 4 f → 4 f absorption lines. • High-resolution infrared absorption measurements for Y 2 SiO 5 :Ce 3+ . • UV fluorescence and absorption spectroscopy of Y 2 SiO 5 :Ce 3+ . • Crystal-field analysis of 4f 1 and 4f5d 1 electronic energy levels of Y 2 SiO 5 :Ce 3+ . • Temperature-dependent linewidth and line shift analysis of Y 2 SiO 5 :Ce 3+ .
