Ce(3+) and Eu(2+) activated Li(2)SrSiO(4) phosphors were prepared using a high temperature solid-state reaction technique. The VUV-UV-vis photoluminescence (PL) of Ce(3+)-doped phosphors Li(2-x)Sr(1-x)Ce(x)SiO(4) and Eu(2+)-doped phosphors Li(2)Sr(1-x)Eu(x)SiO(4), the low-voltage cathodoluminescence (CL) of Eu(2+)-doped phosphor Li(2)Sr(0.991-x)Eu(0.009)SiO(4) and Ce(3+)-Eu(2+) co-doped phosphors Li(2-x)Sr(0.991-x)Eu(0.009)Ce(x)SiO(4) were measured and discussed in consideration of their potential application in field emission displays (FEDs). The intense emission of phosphors Li(2-x)Sr(0.991-x)Eu(0.009)Ce(x)SiO(4) is tunable in yellow to white color gamut under low-voltage cathode ray excitation.
采用高温固态反应技术制备了Ce(3+)和Eu(2+)激活的Li(2)SrSiO(4)荧光粉。测量并讨论了Ce(3+)掺杂荧光粉Li(2-x)Sr(1-x)Ce(x)SiO(4)和Eu(2+)掺杂荧光粉Li(2)Sr(1-x)Eu(x)SiO(4)的真空紫外-紫外-可见光致发光(PL)、Eu(2+)掺杂荧光粉Li(2)Sr(0.991-x)Eu(0.009)SiO(4)和Ce(3+)-Eu(2+)共掺杂荧光粉Li(2-x)Sr(0.991-x)Eu(0.009)Ce(x)SiO(4)的低电压阴极发光(CL)，并考虑了它们在场发射显示器(FEDs)中的潜在应用。在低电压阴极射线激发下，荧光粉Li(2-x)Sr(0.991-x)Eu(0.009)Ce(x)SiO(4)的强发射在黄色到白色色域内是可调的。
