Abstract

Series concentration of Eu²⁺ doped Sr₂SiO₄ were synthesized by traditional high temperature solid method. The phase and luminescence properties of the phosphors were characterized by X-ray diffractometer (XRD) and fluorescence spectrophotometer. The analysis results show that the XRD patterns of phosphors were consistent with Sr₂SiO₄ standard card PDF No.39-1256, illustrated no impurity phase was generated. The luminescence intensity of the phosphors increases first and then decrease with increasing of concentration (molar fraction) of Eu²⁺, when the Eu²⁺ doped concentration is 4%, the luminescence intensity of phosphors is the strongest. The quenching mechanism of phosphors is further studied, the analysis results showed that the quenching mechanism is electric dipole-electric dipole interaction. With increasing of ventilation rate, the luminescence color of the phosphors gradually transitions from blue-green to yellow.
