Abstract:
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.
