The long afterglow blue luminescence materials SrSiO3:Eu2+,Dy3+ are prepared by solid state method with the powdered carbon.Effects of the doping ions Eu2+ content are studied.The tructure,morphology and spectra properties of the samples are characterized by XRD,SEM,UVand PL-PLE spectra,respectively.The results show that sample SrSiO3:Eu2+,Dy3+ is monoclimi structure;the sample pellet is like the bouquet of flowers excitation spectrum is broad in ultraviolet and visible regions;the peaks are 308...
