Abstract

Ce3+ and Eu2+ activated Li2SrSiO4 phosphors were prepared using a high temperature solid-state reaction technique. The VUV-UV-vis photoluminescence (PL) of Ce3+-doped phosphors Li2-xSr1-xCexSiO4 and Eu2+-doped phosphors Li2Sr1-xEuxSiO4, the low-voltage cathodoluminescence (CL) of Eu2+-doped phosphor Li2Sr0.991Eu0.009SiO4 and Ce3+-Eu2+ co-doped phosphors Li2-xSr0.991-xEu0.009CexSiO4 were measured and discussed in consideration of their potential application in field emission displays (FEDs). The intense emission of phosphors Li2-xSr0.991-xEu0.009CexSiO4 is tunable in yellow to white color gamut under low-voltage cathode ray excitation.
