【摘要】 Non-rare earth impurity doped Sr 2 CeO 4:X (X=Zn,Hg,Al,Ag,Cr) phosphors are prepared by using the combustion method.The structural and photoluminescent properties of the as-prepared phosphors are investigated by X-ray diffraction (XRD) and photoluminescence at room temperature.Experimental results show that zinc addition and firing processing can effectively enhance the photoluminescence of Sr 2 CeO 4 phosphors.
