采用高温固相反应法制备了Ce（3+）和Eu（2+）激活的Li（2）SrSiO（4）荧光粉。研究了掺Ce（3+）的Li（2-x）Sr（1-x）Ce（x）SiO（4）和掺Eu（2+）的Li（2）Sr（1-x）Eu（x）SiO（4）的VUV-UV-维斯光致发光（PL），Eu（2+）掺杂Li（2）Sr低压阴极发光对（0.991-x）Eu（0.009）SiO（4）和Ce（3+）-Eu（2+）共掺的Li（2-x）Sr（0.991-x）Eu（0.009）Ce（x）SiO（4）荧光粉进行了测量和讨论，并考虑了它们在场发射显示器（FED）中的潜在应用。在低电压阴极射线激发下，Li（2-x）Sr（0.991-x）Eu（0.009）Ce（x）SiO（4）荧光粉的强发射在黄到白色色域内可调。
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.
