摘要: Ca2 MgSi2 O7 :Ce3+ , :Eu2+ and ,Ce3+ phosphors were prepared using the solid-state reaction method. The crystal structures of sintered melilite type, which has a tetragonal crystallography. chemical compositions was confirmed by energy dispersive X-ray spectroscopy. different thermoluminescence kinetic parameters [activation (E), frequency factor (s) order kinetics (b)] these evaluated compared peak shape Under ultraviolet excitation, emission spectra both composed broad band peaking at 530 nm. When phosphor is co-doped with Ce3+ ions, photoluminescence, afterglow mechanoluminescence intensity strongly enhanced. showed some short persist time. On incorporation efficient transfer from to Eu2+ found intensities increased proportionally increase in impact velocity, suggests that can be used as sensors detect stress an object.
