Abstract

Ce³⁺ doped Sr₂Y₈(SiO₄) ₆O₂ translucent ceramics were successfully fabricated by spark plasma sintering and their photoluminescent properties were studied in correlation with the crystal structure. There are two crystallographic sites A^I and A^II for Ce³⁺ in the Sr₂Y ₈(SiO₄)₆O₂ host and according to the analysis of the photoluminescence spectra, the energy levels of Ce³⁺ at A^I and A^II sites were demonstrated by the configurational coordinate model. The spectroscopic characteristics also indicated that the energy transfer from Ce³⁺ at A^I to those at A^II occurred. This energy transfer became more pronounced with higher Ce³⁺ doping concentration, which is confirmed by the analysis of decay profiles.
