Recently, the photoluminescence of Ce3+ or Eu2+ activated Li2SrSiO4 phosphor has attracted much more attentions for their potential application in white light-emitting diodes (LED).The mixture of the blue emission of Ce3+ and the yellow-green emission of Eu2+ both from Li2SrSiO4 host is promising to produce white light directly without by adding other components.Moreover, the luminescence of Ce3+ and Eu2+ strongly depend on crystal field strength for the spin-allowed and parity-allowed f-d transition.
