摘要	Sr2SiO4:xEu(2+) phosphors were synthesized through the solid-state reaction technique. The crystal phase of Sr2SiO4:xEu(2+) phosphor manipulated by Eu2+ concentration was studied. The phase transited from beta to alpha' in Sr2SiO4:xEu(2+) phosphor with increasing europium concentration. The single beta phase was formed as x <= 0.005 and changed alpha' phase when x>0.01. The emission spectrum of the beta-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 beta-Sr2SiO4:Eu2+ phosphors were fabricated. The luminous efficiency (15.7 1m/W) was higher than alpha'-Sr2SiO4:Eu2+ phosphor white LED.
