摘要	Sr2SiO4:xEu2+ phosphors were synthesized through the solid-state reaction technique. The crystal phase of Sr2SiO4:xEu2+ phosphor manipulated by Eu2+ concentration was studied. The phase transited from to ' in Sr2SiO4:xEu2+ phosphor with increasing europium concentration. The single phase was formed as x [less-than or equal to] 0.005 and changed ' phase when x 0.01. The emission spectrum of the -Sr2SiO4:Eu2+ phosphor consisted of a green-yellow broadband peaking at around 540 nm and a blue band at 470 nm under near ultraviolet excitation. The white LEDs by combining near ultraviolet chips with -Sr2SiO4:Eu2+ phosphors were fabricated. The luminous efficiency (15.7 lm/W) was higher than '-Sr2SiO4:Eu2+ phosphor white LED. 2008 The Chinese Society of Rare Earths.
