摘要：
A series of phosphors M(3-x)Ln(x)MgSi(2)O(8) (M = Ca, Sr; Ln = Ce, Eu; x = 0.005, 0.01, 0.03, 0.05, 0.07, 0.10, 0.15) were synthesized. The luminescence properties in the vacuum ultraviolet-ultraviolet visible spectral range and the X-ray excited radioluminescence were investigated in detail. The results reveal that the M(3-x)Ln(x)MgSi(2)O(8) (M = Ca, Sr; Ln = Ce, Eu) phosphors exhibit typical broad excitation and emission bands, which are ascribed to the 4f-5d transitions of the Ce3+ and Eu2+ ions. Finally, X-ray excited luminescence (XEL) spectra were measured to evaluate the possibility of Sr3MgSi2O8:Ce3+ and Sr3MgSi2O8:Eu2+ as scintillation materials.
