采用高温固相反应法制备了Li 2 CaSiO 4: Eu 2+荧光粉。研究了紫外-可见光致发光和低压阴极致发光。最佳荧光粉li2ca 0.991 Eu 0.009 sio4 （LCS-Eu）在低压阴极射线激发下呈现出强烈的青色发射，色坐标在（0.119,0.203）附近。因此，通过将这种荧光粉与RGB三色荧光粉结合，有望扩大fed的色域。
Li 2 CaSiO 4: Eu 2+ phosphors were prepared using a high temperature solid-state reaction technique. The VUV-vis photoluminescence and low-voltage cathodoluminescence were investigated. The optimal phosphor Li 2 Ca 0.991 Eu 0.009 SiO 4 (LCS-Eu) shows intensive cyan-emitting with color coordinates around (0.119, 0.203) under low voltage cathode ray excitation. Therefore, the color gamut of FEDs is expected to be enlarged by combining this phosphor with RGB tricolor phosphors.
