Luminescence properties and identification of the crystallographic sites of Ce3+ in LiGd9(SiO4)6O2
چکیده انگلیسی
A series of LiGd9-x(SiO4)6O2:xCe3+ phosphors were prepared by a conventional high temperature solid state reaction method, and their spectroscopic characteristic were systematically investigated. The results showed that two types of Ce3+-emitting centers with emission at about 390 and 430 nm existed in the phosphors LiGd9(SiO4)6O2:Ce3+. The Stokes shift and crystal field depression of Ce(1) and Ce(2) were investigated. The concentration quenching effect and the critical distance of energy transfer were determined.
