Abstract

Abstract A potential green emitting phosphor Ca 8 Mg(SiO 4 ) 4 Cl 2 :Eu 2+ was prepared by modified sol–gel method. The factors those affect the photoluminescence intensity including heating temperature, the usage of the chlorine source CaCl 2 and the concentration of dopant Eu 2+ were also investigated in detail. As comparison, the phosphor prepared by solid-state reaction was also prepared. The phosphors show intense absorption in the range of 375–450 nm, which makes it a potential candidate of green emitting phosphor used for near-UV or blue light excited white LEDs.
