Synthesis of Blue-Green Phosphors Sr4Si3O8Cl4:Eu2+ by Gel-Combustion Method and Their Luminescent Properties
Sr4Si3O8Cl4:Eu2+ blue-green phosphors were synthesized by the gel-combustion method. The as-synthesized phosphors were analyzed and characterized by X-ray diffraction and fluorescence spectrophotometer. The results indicate that orthorhombic phase Sr4Si3O8Cl4:Eu2+ has been formed after the precursor...

| description | Sr4Si3O8Cl4:Eu2+ blue-green phosphors were synthesized by the gel-combustion method. The as-synthesized phosphors were analyzed and characterized by X-ray diffraction and fluorescence spectrophotometer. The results indicate that orthorhombic phase Sr4Si3O8Cl4:Eu2+ has been formed after the precursor calcined at 900°C
reductive temperature. The excitation spectrum of Sr4Si3O8Cl4:Eu2+ is a broad band in the range of 250 ~ 450 nm and the main peak at 324 nm. The emission spectrum is also a broad band with the main emission peak at about 484 nm, which is ascribed to the typical 4f5d1
to 4f7
transition of Eu2+. Moreover, the effects of the concentration of Eu2+, the reductive temperature, and the doping amount of Mg2+ on luminescent properties were discussed. |
