چکیده انگلیسی
Effect of RE3+ as a co-dopant in long-lasting phosphorescence CdSiO3:Mn2+ (RE=Y, La, Gd, Lu) has been investigated. A longer orange emitting phosphorescence phenomenon was observed in the co-doped CdSiO3:Mn2+,RE3+ phosphors after exciting with ultraviolet (UV) light. The luminescence properties, including photoluminescence (PL) spectra and thermoluminescence (TL) spectra, as well as the afterglow decay curves, were studied. The results revealed that one of the origins of the improvement is due to nonequivalent substitution to produce more e-traps, and energy transfer from Gd3+ to Mn2+ to boost the performance of CdSiO3:Mn2+,Gd3+. Role of RE3+ co-doped into CdSiO3:Mn2+ matrix and the possible long-lasting phosphorescence process are discussed in this paper.
