Abstract
Li 4(Sr 0.96Eu 0.04)(Ca 1 − x Mn x )(SiO 4) 2 phosphors were synthesized by solid-state reactions and photoluminescence (PL) properties were investigated. These phosphors have intense absorption in n-UV region, which is suitable for excitation of UV LEDs. The orange-reddish emission of Mn 2+ can be adjusted by changing the Mn 2 + / Eu 2 + ratio. Energy transfer from Eu 2+ to Mn 2+ is observed. Li 4(Sr 0.96Eu 0.04)(Ca 1 − x Mn x )(SiO 4) 2 phosphors could be used in white LEDs.
